Stiffness • Toe Ache • Heel Ache • Numbness and Tingling • Swelling • Pores and skin Issues
Because the literal basis of our our bodies, our ft are essential to conserving us energetic and wholesome. It’s simple to take these workhorse appendages as a right, however when issues come up, the ripple results make the ft exhausting to ignore.
“When one thing goes fallacious in your foot, your complete physique normally has to cope with it,” says biomechanist Katy Bowman, MS, creator of Easy Steps to Foot Ache Aid. Even a small space of soreness or irritation may be sufficient to maintain you out of your day by day stroll or trigger different physique components to compensate in ways in which result in additional points.
“The common particular person takes hundreds of steps day-after-day, and if there’s one thing slightly bit off within the biomechanics — which means the construction or operate of the foot — it gained’t simply have an effect on the foot; it’s going to have a domino impact all the way in which up the physique,” notes Robert Kornfeld, DPM, a holistic podiatrist on the Continual Foot Ache Heart in New York Metropolis. The reverse can be true: It’s not unusual for knee, hip, and again ache to resolve after foot points are addressed.
Many people are unaware that the ft may be harbingers of systemic well being issues. “The foot is a mirror of what’s happening in the remainder of the physique. Podiatrists are sometimes the primary ones to diagnose vascular and neurological issues, thyroid situations, and diabetes,” Kornfeld says.
Let’s delve into six frequent foot complaints and the systemic points they could be signaling, plus methods for addressing them.
1) Stiffness
Potential causes: Inactivity, irritation from arthritis, constrictive footwear
The primary contributor to stiff ft additionally results in rigid shoulders and hips — lack of standard and thorough motion. “Although the foot is small, it has numerous hinges, and every of these hinges must be moved,” Bowman says.
Sitting for hours is surprisingly exhausting on the ft. “Inactivity, which tightens the hips and pelvis, can then tighten the ft, as a result of your ft and hips are very a lot related,” says Emily Splichal, DPM, a functional podiatrist on the Heart for Useful and Regenerative Podiatric Medication in Chandler, Ariz.
Systemic irritation, usually a characteristic of arthritis, additionally contributes to stiff ft. “Irritation may be considered stickiness — it causes numerous soft-tissue adhesions,” says Splichal. Common motion reduces stickiness and retains the joints of the decrease physique robust and versatile.
Footwear is one other essential participant. “More often than not, our ft are wrapped in one thing very stiff that immobilizes their components,” Bowman notes. Think about sporting tight, inflexible mittens in your palms day-after-day: Your wrists and forearms would compensate as you discovered to make use of every hand as a single digit, dropping the muscular management and suppleness to separate them into their constituent components. That is primarily what trendy footwear has achieved to our ft.
“In contrast with our ft’s pure, unshod state, our footwear are stiff, normally prop our heels above our toes, and depart no room for our toes to maneuver,” Bowman says. This results in weak, underdeveloped foot muscle groups and places stress on the decrease leg, in addition to on the joints, fascia, and ligaments within the ft.
“Our ft, in footwear and on flat concrete, are kind of like our digestion on a crappy eating regimen — they’re starved of the nutritious motion inputs they want for well being,” she notes.
Foot arches which can be both flat and weak or excessive and tight are additionally an indication of inflexibility. Bowman describes the arch as an motion by the muscle groups within the ft and hips. A flat foot signifies a scarcity of the energy wanted to create an arch, whereas excessive, rigid arches can level to extreme rigidity.
Both can cease the midfoot from stretching out and springing again up once more to cushion our steps. And each may be helped with workout routines to construct energy and suppleness within the ft. (For feet-strengthening workout routines, see “Energy Coaching for Your Ft.”)
2) Toe Ache
Potential causes: Gout, bunions, ingrown toenails
If you assume “toe ache,” eating regimen may not be the primary wrongdoer that springs to thoughts. However diet-related gout, an inflammatory situation that causes swelling and ache within the joints, usually reveals up first within the foot. “It’s a pink, sizzling, infected big-toe joint the place even the blankets in your mattress are sufficient to trigger ache,” Splichal explains.
Gout can have a genetic part, however eating regimen is normally the most important contributing issue. Crimson meat, seafood, sweetened drinks, and alcohol all comprise excessive ranges of compounds referred to as purines, which the physique breaks down into uric acid. These acid crystals can accumulate within the joints, resulting in ache and irritation. Dietary modifications are the primary line of protection right here. (For extra on uric acid, see “Uric Acid: A New Metric for Coronary heart Well being.”)
However, a bunion — which seems as a bony bump on the joint on the base of the large toe — is normally a “purely biomechanical situation,” Kornfeld says. Bunions can kind resulting from gait patterns, instability within the first metatarsal (the bone extending towards your ankle from the large toe), and overpronation, and they’re exacerbated by slender footwear that power the large toe towards the pinky. They have an inclination to happen extra ceaselessly in ladies and older individuals, probably resulting from comparatively weaker connective tissue and the cumulative results of biomechanical dysfunction.
If the ligament holding the primary metatarsal is free or unstable (probably from inadequate collagen, which stabilizes ligaments), it may well trigger retrograde forces to push the bone out to kind a bunion. However corrective workout routines can enhance joint stability, even in individuals with a genetic tendency towards decrease collagen ranges.
And minimizing time in excessive heels, which put the physique’s weight proper over the big-toe joint, may be preventive. “Intervention is important within the early phases of bunion formation so it doesn’t progress right into a deformity that creates issues sporting footwear, causes ache, and limits exercise,” Kornfeld says.
Ingrown toenails, during which the borders of the nail flip downward and dig into the pores and skin, are a typical reason behind toe irritation, redness, swelling, and ache. Once more, tight footwear may be accountable, Splichal explains. “In case your footwear are pushing the sting of the nail into the pores and skin, that would contribute to an ingrown nail.”
Bunions could be a issue right here, too, due to how they modify the angulation of the step and push the nail into the pores and skin. And chopping toenail corners too aggressively permits the pores and skin to raise above the nail border, so the nail grows into the pores and skin. Podiatrists suggest chopping toenails straight throughout to keep away from this.
“I’d additionally encourage a affected person to make use of toe spacers if they’ve a bunion, discover better-fitting footwear that don’t push the nail in, and probably put urea on the nail to melt it so it’s not so exhausting and painful,” says Splichal.
3) Heel Ache
Potential trigger: Plantar fasciitis
Plantar fasciitis is irritation of the thick band of fascia that runs from the heel bone to the toes. It may be brought on by a one-time occasion during which you overload the tissue, similar to strolling for miles on trip in new footwear. Or it may well develop over an extended interval in response to posture or mobility points within the ft, says Bowman.
“Plantar fasciitis is biomechanical in origin,” Kornfeld explains. “One typical trigger comes from the calf muscle being overly tight in compensation for hypermobility within the forefoot. The tighter the calf muscle will get, the higher the pull and stress on the plantar fascia, which might injure cells and trigger them to turn out to be chronically infected.” Small tears may develop within the plantar fascia, including to ache and irritation.
The antidote, says Bowman, is mobilizing and stretching the foot. “You’ve acquired this stiff, tense wad of injured tissue, and also you need to stretch and clean it out like a ball of dough.” She suggests utilizing focused stretches and rolling the foot out on a ball. “These are methods of waking up this tissue that’s clumped to guard itself.”
Different methods embody getting a biomechanical analysis to assist establish problematic gait and posture habits, altering your footwear, and making an attempt acupuncture.
Whereas some could profit from taping or utilizing an orthotic or brace, Bowman stresses the significance of figuring out the underlying trigger. “You need to get your foot working higher for you with out all that gear, or else you’re not likely attending to the basis of the issue.”

4) Numbness and Tingling
Potential trigger: Peripheral neuropathy
When nerves within the palms and ft are broken, peripheral neuropathy may end up. Signs embody numbness, tingling, lack of stability, weak spot, or a wound on the foot that gained’t heal.
Diabetes (each sort 1 and kind 2) is the most typical set off: Excessive blood-sugar ranges can injury nerves over time. Different potential causes embody vitamin B12 deficiency, bodily damage to the nerves, chemotherapy, remedy unwanted side effects, ingesting an excessive amount of alcohol, or viral sickness.
“I’ve fairly a couple of sufferers who developed post-COVID peripheral-nerve irritation and signs,” notes Splichal. Shingles can be recognized to be a possible set off for neuropathic ache or numbness. Lupus, rheumatoid arthritis, and different autoimmune situations can contribute by creating irritation in peripheral nerves.
Key to reduction from all these situations is decreasing that inflammation. Splichal recommends an anti-inflammatory eating regimen that helps secure blood sugar, nutrient stability, and microcirculation. “All of our blood vessels have tiny branches that go to the nerves, so you want to consider microcirculation to help nerve well being,” she says.
Splichal additionally treats her neuropathy sufferers with red-light remedy. And a few individuals discover transcutaneous electrical nerve stimulation (TENS) and acupuncture useful.
5) Swelling
Potential trigger: Fluid retention
Swollen ft and ankles could also be associated to edema, when an excessive amount of fluid turns into trapped within the physique’s tissues. Edema may be brought on by poor venous return (when the physique’s potential to pump blood up and away from the ft is compromised), consuming an excessive amount of salt, being pregnant, being premenstrual, or sitting or standing in place for too lengthy.
It might even be a aspect impact of sure drugs or an indication of insulin resistance. “Uncontrolled blood sugar creates free radicals and irritation that damages collagen within the blood vessels, so that they begin to lose integrity,” Splichal says.
Edema can sign much more critical situations, together with problems with the kidneys, liver, or coronary heart. When you have persistent swelling in your ft and ankles, it’s sensible to test along with your healthcare supplier.
Regardless of the underlying situation, swelling within the ft and ankles is normally relieved by elevating them. And whereas taking a stroll can generally enhance swelling (particularly in sizzling climate), strolling supplies a internet profit. The calves are generally known as the “second coronary heart” due to the function they play in pumping blood via the decrease a part of the physique.
“The ft, being farthest away from the center, run the best danger of poor circulation; your cardiovascular system relies upon closely on the motion of the muscle groups within the ft and decrease legs,” writes Bowman in Easy Steps to Foot Ache Aid.
The easiest way to lend the center a hand is to get transferring. “You want a pumping mechanism to get the blood again as much as the center, and strolling is an effective way to activate that calf pump,” Splichal explains. (For extra in your calves and cardiovascular well being, see “The Shocking Connection Between Your Calves and Coronary heart Well being.“)
6) Pores and skin Issues
Potential causes: Plantar warts, fungal infections, intestine dysbiosis, thyroid points
Our ft are topic to a number of rubbing, friction, and make contact with with moist environments, from the insides of our socks to the bathe ground on the fitness center. Whereas blisters and calluses may be dealt with with slightly TLC and a change of footwear, warts and chronic fungal infections are more durable nuts to crack.
“Plantar warts are related to the human papillomavirus [HPV],” Splichal notes. Genetics and general immune standing can have an effect on how nicely somebody fights HPV. Some could develop small warts that self-resolve, whereas others find yourself in lengthy battles with warts that refuse to vanish.
“Warts like darkish, moist environments,” she says. “When you’re conserving your ft in socks for 10 hours a day, that’s an ideal breeding surroundings.” She suggests exposing your ft to open air as a lot as attainable to dry them out.
Splichal additionally cautions in opposition to choosing at a plantar wart, as a result of they will unfold to your palms or your different foot.
For small warts, making use of a topical salicylic acid may do the trick, she notes. “However after they get bigger, you need to go to a podiatrist or dermatologist to allow them to freeze or burn it off.”
In the meantime, dry, itchy pores and skin on the ft normally indicators fungal an infection. Fungus can infect the nails, the pores and skin between the toes, or the underside of the foot. “They’re all handled slightly bit in another way,” Splichal says.
An an infection beneath the nail may require oral drugs. “When you simply put one thing topical on, it’s exhausting for the remedy to get via the exhausting nail to succeed in it.”
Treating a fungal an infection that begins between the toes and spreads, similar to athlete’s foot, requires conserving moisture-prone areas dry. These infections can normally be handled with antifungal lotions or sprays. Tea tree oil is a pure antifungal therapy for athlete’s foot.
Some suppliers see fungal infections on the ft as an indication of intestine dysbiosis and an extra of fungus within the GI tract. “Once we tackle what’s happening at a intestine degree, now we have a significantly better alternative to eliminate it,” Kornfeld notes.
Lastly, itchy ft can often sign an issue with the thyroid. “Thyroid dysfunction causes issues [with] replenishing and changing pores and skin cells,” he explains. That may lead to dry and lifeless cells accumulating on the floor of the pores and skin, inflicting itchiness.
Discover Your Stride
Noting that prevention is one of the best treatment of all, Splichal presents these 4 suggestions for day by day foot upkeep:
- Launch rigidity within the ft with energetic stretches or therapeutic massage.
- Activate the muscle groups with easy workout routines.
- Interact the foot muscle groups and create stability with single-leg balancing for 10 seconds on all sides.
- Stimulate sensation by spending time barefoot.
Bowman reminds us that our ft deserve no less than as a lot consideration as our different physique components. “When you do pull-ups or upper-body workout routines, ensure you’re giving your ft the identical courtesy. You’re going to ask extra out of your ft than you’re out of your arms and shoulders all through your lifetime.”
Why Go Barefoot?
To develop robust muscle groups, dense bones, and wholesome nerves, our ft should be labored similar to different physique components. That’s why some podiatrists suggest spending as a lot time as attainable barefoot — or in minimalist footwear that protects the pores and skin and permits the foot its full vary of movement.
“Tissue must really feel load in an effort to adapt,” explains biomechanist Katy Bowman, MS, creator of Rethink Your Place. “When you’ve cushioned and immobilized your ft with inflexible footwear, they now not really feel load. So, you’re placing the weakest a part of you beneath your whole physique weight.”
Nonetheless, don’t simply chuck your Chucks and head out for a barefoot dash. “There’s numerous transitional work wanted should you’ve been sporting footwear for many years,” she cautions. “Workouts and consciousness can assist you transition efficiently.” (For extra on barefoot coaching, see “Naked Your Sole: Barefoot Coaching.”)
