Understanding the Different Types of Heel and Foot Pain

Plantar fasciitis is the most common cause of heel pain, but it is not the only one. If your symptoms don't match the textbook pattern, the reason may simply be that the textbook is describing a different condition.

This is a tour of the most common foot-pain presentations, organised by where it hurts. It is a differential-diagnosis primer for patients — enough to know what to suspect and when to ask a clinician for a proper work-up. It is not enough to self-diagnose with confidence, and it shouldn't be.

Heel pain

Plantar fasciitis

The classic: first-step pain, tender at the inside of the heel, eased by movement, worse with prolonged standing. Covered in depth in our main guide. 70–80% of undifferentiated heel pain in adults.

Heel fat pad syndrome

The fat pad under your heel — a layer of septa and fat that acts as a natural shock absorber — thins with age, repetitive impact, or after corticosteroid injection. Pain is in the middle of the heel (not the inside edge), feels deep and bruise-like, and is worse on hard surfaces. Unlike plantar fasciitis, it isn't worse on the first step — it's worse with every step.

Calcaneal stress fracture

A tiny crack in the heel bone, usually from a spike in impact activity. Pain is constant (not just loading-related), worse at night, and reproducible by squeezing the heel from side to side (not just pushing up on it). Needs imaging. Do not power through a suspected stress fracture.

Baxter's nerve entrapment

Compression of the first branch of the lateral plantar nerve, often at the inside edge of the heel. The pain mimics plantar fasciitis but has a burning, shooting quality and sometimes radiates along the arch. Around 15–20% of chronic, treatment-resistant heel pain turns out to be this. Often missed.

Achilles insertional tendinopathy

Pain at the back of the heel where the Achilles meets the bone. Worse after rest, worse uphill, and tender when you pinch the tendon just above the heel. Distinct from plantar fasciitis because the pain is posterior, not plantar (underside).

Arch pain

Plantar fasciitis with arch involvement

Standard plantar fasciitis can refer pain along the arch, not just the heel. If the heel is the epicentre and the arch is the echo, it's still fasciitis.

Posterior tibial tendon dysfunction

The posterior tibial tendon holds up the arch. When it fails — usually gradually in middle-aged adults, especially women — pain settles along the inside of the ankle and the inner arch. The arch may visibly drop. This one needs prompt management; untreated, it progresses to fixed flat foot and significant disability.

Midfoot osteoarthritis

Aching, stiffness in the middle of the foot, worse with activity, better with rest. Often in people over 50 or those with a history of midfoot injury. Mornings may be stiff; stiffness eases with movement, similar to PF, but pain is in the dorsum (top) rather than the plantar surface.

Forefoot pain

Metatarsalgia

Aching, burning pain under the ball of the foot, often with a sensation of "walking on a pebble." Caused by excess load on the metatarsal heads — typically from high heels, very thin soles, or biomechanics that shift load forward.

Morton's neuroma

A thickening of the nerve between the toes (usually between the third and fourth). Pain is often described as electric, burning, or like having a pebble in the shoe. Worse in narrow shoes. Relieved by taking shoes off and squeezing the forefoot from side to side (the Mulder's click).

Sesamoiditis

Inflammation of the two tiny sesamoid bones beneath the big toe joint. Pain sits directly under the big toe, especially on push-off. Common in dancers, runners, and anyone who repeatedly loads the forefoot.

Hallux rigidus

Arthritis of the big toe joint. Stiffness and pain at the base of the big toe, worse when bending the toe upward. Reduces push-off mechanics, which can cascade into plantar fascia issues too.

Whole-foot and systemic

Peripheral neuropathy

Numbness, tingling, burning — often in a stocking distribution (both feet, worse distally). Most commonly diabetic; also seen in chemotherapy, alcohol use, B12 deficiency. Needs medical review, not self-care.

Inflammatory arthropathies

Rheumatoid arthritis, psoriatic arthritis, gout — each can present as foot pain first. Red flags include morning stiffness >60 minutes, symmetrical joint involvement, joint swelling, or pain in multiple joints. Blood tests and a rheumatologist visit are the right path.

Circulation problems

Peripheral arterial disease causes cramping or aching pain with walking that resolves with rest (intermittent claudication). Distinct from fascia pain. More common in smokers and older adults. Worth a GP review.

What to ask yourself

When working out what you are likely dealing with, these questions narrow the field fast:

1. Where exactly does it hurt? Point with one finger. Heel, arch, forefoot, or top? Inside or outside edge?
2. When does it hurt? First step, after activity, all day, at night?
3. What makes it better or worse? Movement, rest, heat, cold, specific shoes?
4. What is the quality of the pain? Sharp, dull, burning, tingling, bruise-like?
5. How did it start? Gradual over weeks, or sudden? After a specific event, or out of nowhere?

The answers shape the likely diagnosis. A few minutes with a notebook before an appointment helps the clinician enormously. For the at-home version of the examination, see our 90-second foot self-assessment. For when to escalate to a professional, our podiatrist referral guide.
