Why Do I Have Pain in My Feet? Causes by Location

Where your foot hurts is one of the best clues to why it hurts. The foot contains 26 bones, more than 30 joints, and over a hundred tendons and ligaments, and different structures tend to fail in predictable ways depending on their location and the loads they bear. A sharp ache under your heel first thing in the morning points toward very different problems than a burning sensation between your toes or a deep throb behind your ankle. This guide walks through the foot region by region, covering the most common causes of pain in each area and what distinguishes them from one another.

Pain Under the Heel

The most common reason for pain on the bottom of the heel is plantar fasciitis, a condition affecting the thick band of tissue that runs from your heel bone to the base of your toes. It tends to feel worst with the first steps after getting out of bed, then gradually eases as the tissue loosens up. Traditionally described as inflammation from repetitive strain, the picture is more complicated than that: tissue samples from people with chronic cases rarely show actual inflammation, suggesting the problem is more about degenerative changes in the tissue than an ongoing inflammatory process.

1PubMed. The pathomechanics of plantar fasciitis

Heel spurs often come up in conversation about plantar heel pain, and they deserve some demystifying. A calcaneal spur is a small bony projection on the underside of the heel bone, visible on X-ray. One study found spurs in about 85% of painful feet but also in roughly 72% of feet that had no pain at all.

2Turkish Journal of Medical Sciences. Do the presence, size, and shape of plantar calcaneal spurs have any significance in terms of pain and treatment outcomes in patients with plantar fasciitis?

So having a spur does not automatically mean it is the source of your discomfort. Spur size and symptom duration do seem to correlate with pain severity, and certain spur shapes may be more problematic than others.

But many people walk around with spurs and never feel a thing, which means a spur on your X-ray might be an incidental finding rather than the smoking gun.

Pain in the Arch

Arch pain often overlaps with plantar fasciitis, since the plantar fascia spans the entire arch. But when the ache sits more along the inner edge of the arch or behind the ankle bone on the inside, a different structure may be involved: the posterior tibial tendon. This tendon is the main support for your foot’s medial arch, and when it degenerates or tears, your arch can gradually flatten. Posterior tibial tendon dysfunction is the most common cause of adult-acquired flatfoot deformity, and it tends to develop slowly, often starting as vague soreness along the inner ankle and arch before progressing to noticeable changes in foot shape.

5PubMed Central. Posterior Tibial Tendon Dysfunction: An Overview

The distinction matters because the treatment paths diverge. Plantar fasciitis usually responds to stretching, supportive footwear, and time. Posterior tibial tendon dysfunction, especially once the arch has collapsed, can require bracing or surgery to prevent further deformity. If your arch pain is accompanied by a sense that your foot is getting flatter or your ankle is rolling inward more than it used to, the posterior tibial tendon is worth investigating.

Ball of the Foot and Forefoot

Pain under the ball of the foot, the padded area behind your toes, is broadly called metatarsalgia. It is not a single diagnosis but a description of where it hurts. The actual cause depends on what is going wrong underneath.

One of the more distinctive forefoot conditions is Morton neuroma, which produces a burning pain between the toes, most often between the third and fourth. Despite the name, it is not actually a nerve tumor. Histological examination shows perineural fibrosis, meaning scar-like tissue building up around the nerve rather than the nerve itself growing abnormally.

6PubMed. The diagnosis and management of Morton’s neuroma: a literature review

The classic symptom is a sensation like standing on a pebble or a fold in your sock, along with burning or numbness radiating into the affected toes.

7JAMA. Common Painful Foot and Ankle Conditions: A Review

Tight, narrow shoes compress the metatarsal heads together and squeeze the nerve, which is why the condition is strongly associated with footwear that crowds the toes. High heels are a particular offender: by shifting body weight forward and hyperextending the toe joints, they place the nerve under mechanical compression between the metatarsal heads.

Less common but easy to miss is sesamoiditis, pain and inflammation at the two small bones embedded in the tendons beneath the big toe joint. These pea-sized bones act as pulleys for the tendons that flex the big toe, and they absorb a lot of force during push-off. When they become irritated or fractured, you will feel a deep ache right under the ball of the foot near the big toe, especially when bending the toe upward or pushing off during walking.

The sesamoids can develop problems from a range of causes including trauma, arthritis, infection, and even reduced blood supply.

Toe Pain

The big toe joint is one of the most pain-prone spots on the entire foot, and the two most common culprits there are bunions and gout.

A bunion, or hallux valgus, is not just a bump. It is a three-dimensional shifting of the big toe joint in which the toe drifts toward the smaller toes while the metatarsal bone angles outward, creating that characteristic bony prominence on the inner edge of the foot.

11PubMed Central. Hallux Valgus

This deformity can cause considerable pain, especially when shoes press against the prominence, and it progressively alters the mechanics of the joint.

Gout, on the other hand, tends to announce itself explosively. A classic gout attack at the base of the big toe, known historically as podagra, involves sudden, severe pain that can wake you from sleep, with the joint turning red, hot, and swollen. Researchers have found that the big toe joint is particularly vulnerable to gout for several overlapping reasons: the foot is cooler than the body’s core, which helps uric acid crystals form more easily; the joint is subject to repeated minor physical stress from walking; and the big toe joint is prone to osteoarthritis, which creates cartilage surfaces where crystals deposit more readily. Overnight, fluid in the joint may reabsorb while uric acid stays behind, concentrating it and triggering crystal formation.

12PubMed Central. Revisiting the pathogenesis of podagra: why does gout target the foot?

Smaller toe pain often comes down to hammertoes, a deformity in which one or more of the lesser toes bend abnormally at the middle joint, curling downward instead of lying flat. The underlying problem is an imbalance between the muscles and tendons that control the toe. As it progresses, the bent joint rubs against the top of your shoe, producing painful corns and calluses, and walking becomes increasingly uncomfortable.

Top of the Foot

Pain on the top, or dorsal surface, of the foot tends to get less attention than sole-of-the-foot problems, but it can be just as limiting. One major category is midfoot arthritis, which affects the joints in the middle of the foot where the long metatarsal bones meet the tarsal bones. This is an area that absorbs a lot of bending and twisting force during walking. Most cases stem from either a previous injury (a Lisfranc or other midfoot fracture) or straightforward wear-and-tear osteoarthritis, though inflammatory conditions and nerve-related joint damage can also be involved.

14PubMed Central. Midfoot arthritis- current concepts review.

Athletes and active people with a vague, hard-to-pinpoint ache on the top of the midfoot should also consider a navicular stress fracture. The navicular bone sits at the peak of the arch on the inner side of the foot and acts as a keystone, bearing a large share of the arch’s load. Its central zone has a relatively poor blood supply, which makes it slow to heal and particularly susceptible to stress injuries.

15PubMed Central. Navicular Stress Fractures: A Narrative Review of Pathoanatomy, Diagnostic Pitfalls, and Management

These fractures are notoriously easy to miss on plain X-rays and often require more advanced imaging to diagnose. If you have a nagging top-of-foot ache that worsens with activity and improves with rest, and it has been hanging around for weeks, a stress fracture deserves a spot on the list of possibilities.

Back of the Heel

Pain at the back of the heel, where the Achilles tendon meets the heel bone, often gets lumped under the vague label “Achilles problems,” but there is a specific mechanical condition here worth knowing about: Haglund syndrome. This involves a prominent bump on the back of the calcaneus (the heel bone) that creates friction against the Achilles tendon and the bursa tucked between them. The result is a combination of bony prominence, tendon irritation, and bursitis that produces pain right at the back of the heel, especially when wearing rigid-backed shoes.

16PubMed Central. Haglund Syndrome: A Mechanical Cause of Posterior Heel Pain

Achilles tendinopathy, by contrast, usually affects the tendon itself a few centimeters above where it attaches to the bone. The distinction is practical: Haglund syndrome tends to worsen with shoe pressure and may respond to changing footwear, while midsubstance Achilles tendinopathy responds better to eccentric loading exercises. Both can coexist, which muddies the clinical picture, but paying attention to exactly where on the back of your heel the pain sits helps sort them out.

Inner and Outer Ankle Pain

Pain on the inner side of the ankle, especially if accompanied by tingling, burning, or numbness on the sole of the foot, may be tarsal tunnel syndrome. The tarsal tunnel is a narrow channel on the inside of the ankle through which the posterior tibial nerve passes. When that nerve gets compressed, it produces symptoms very similar to carpal tunnel syndrome in the wrist: pain, numbness, and a burning or tingling sensation radiating into the heel and sole.

17PubMed Central. Tarsal Tunnel Syndrome – A Comprehensive Review

The compression can come from swelling, a cyst, varicose veins, or even flat feet that stretch the nerve repeatedly.

18PubMed Central. An Update on Posterior Tarsal Tunnel Syndrome

On the outer side of the ankle, persistent pain after what seemed like a simple ankle sprain could be a peroneal tendon problem. The peroneal tendons run behind the outer ankle bone and help stabilize the foot. Injuries to these tendons are underappreciated and frequently mistaken for chronic ankle ligament sprains, partly because the symptoms overlap: lateral ankle pain, a feeling of instability, and discomfort during activity. When left untreated, peroneal tendon disorders can cause ongoing pain and significant functional problems.

19SAGE Journals (PubMed Central / American Journal of Sports Medicine). Tendon disorders of the foot and ankle, part 1: peroneal tendon disorders

Another outer-ankle condition that can follow repeated sprains is sinus tarsi syndrome. The sinus tarsi is a small cavity on the outside of the foot just in front of the ankle bone. Excessive motion at the subtalar joint, the joint beneath the ankle, can irritate this space, producing localized pain right at the opening of the cavity along with a feeling of instability, especially on uneven ground.

20PubMed Central. Examination and intervention for sinus tarsi syndrome

When the Whole Foot Burns or Tingles

Not all foot pain points to a local structural problem. Diffuse burning, tingling, or numbness that follows a “stocking” pattern, affecting both feet symmetrically from the toes upward, is the hallmark of peripheral neuropathy. Diabetes is the most common cause. Diabetic neuropathy can present as an acute, intensely painful syndrome where the pain is severe but standard nerve tests show minimal abnormality, or as a chronic form where pain is accompanied by patchy sensory loss and wasting of the small muscles in the feet.

21PubMed. Diabetic neuropathies and pain

Rheumatoid arthritis can also reshape the foot in painful ways. The inflammatory process attacks joint linings throughout the body, and in the forefoot this typically leads to bunions and deformities of the lesser toe joints. Despite advances in medication, forefoot deformity remains a common problem in people with rheumatoid arthritis and can require surgery when the pain becomes disabling.

22PubMed Central. Rheumatoid forefoot deformity: pathophysiology, evaluation and operative treatment options.

If your foot pain is not confined to one spot, or if it is accompanied by numbness, changes in skin color, or joint swelling that migrates, those are signals that a systemic condition rather than a local injury may be driving the problem. A healthcare provider can sort this out with blood work and nerve testing.

How Shoes Shape Foot Pain

Footwear is a thread that runs through nearly every condition described above, so it is worth addressing on its own. High heels shift the body’s center of gravity forward, concentrating pressure under the metatarsal heads rather than distributing it across the foot. Studies measuring in-shoe pressure confirm that the forefoot pressure peak increases significantly with heel height, with the highest loads landing under the first and second metatarsal heads.

23PubMed Central. Change of In-Shoe Plantar Pressure According to Types of Shoes (Flat Shoes, Running Shoes, and High Heels)

This helps explain why forefoot problems like metatarsalgia, Morton neuroma, and bunions are so strongly linked to high-heeled and narrow-toed shoes.

A study comparing women who regularly wore narrow-toed high heels with those who did not found that roughly 79% of the heel-wearing group reported pain in the feet, knees, or back, compared to about 53% of those who did not wear them.

24Cukurova Medical Journal. Determination of lower extremity anthropometric measurements in adult healthy women wearing and non-wearing narrow toed high heeled shoes

That gap is substantial, and it underscores how much shoe design affects not just the foot itself but the entire lower limb chain.

The Evolutionary Angle

One reason the human foot is so susceptible to pain in the first place is that it is an evolutionary work-in-progress. The foot’s architecture is highly specialized for bipedal walking and standing, a design inherited from ancestors who made the transition from four-legged to two-legged locomotion. That specialization is impressive but leaves very little margin for error: even small deviations from the established structural pattern, whether from genetics, injury, or footwear, can produce significant clinical problems.

We are, in a sense, paying a biomechanical tax for walking upright, and many of the foot conditions people develop are consequences of that ancient trade-off.
