Heel pain is most commonly caused by plantar fasciitis, a condition where the thick band of tissue running along the bottom of your foot becomes irritated from repeated stress. But several other conditions can produce nearly identical symptoms, and telling them apart matters because the fixes are different. Where exactly you feel the pain, when it’s worst, and how it behaves throughout the day are the biggest clues to what’s going on.
Plantar Fasciitis: The Most Common Cause
The plantar fascia is a tough strip of connective tissue that spans from your heel bone to the base of your toes, acting like a bowstring that supports your arch. When this tissue is subjected to repeated stretching and stress, small tears develop. Over time, those micro-tears trigger inflammation and thickening of the fascia, producing a stabbing pain concentrated right under the heel bone where the fascia attaches.
The hallmark symptom is intense pain with your first steps in the morning. During sleep, your foot relaxes into a pointed position, letting the fascia tighten and shorten. When you stand up, that shortened tissue is suddenly forced to stretch under your full body weight, pulling on the damaged area. The pain typically fades after a few minutes of walking as the tissue loosens, then returns after long periods of sitting or standing.
Risk factors include spending long hours on your feet, a sudden increase in activity, tight calf muscles, higher body weight, and shoes with poor arch support. Runners and people who work on hard floors are especially prone to it.
Achilles Tendinitis: Pain at the Back of the Heel
If your pain is at the back of your heel rather than the bottom, the Achilles tendon is the likely culprit. This tendon connects your calf muscles to your heel bone and absorbs force every time you push off the ground. There are two distinct types, and they behave differently.
Insertional Achilles tendinitis affects the spot where the tendon meets the heel bone, at the very lowest part of the back of your heel. It can develop even in people who aren’t particularly active and sometimes produces a bony bump at the attachment point. Non-insertional tendinitis involves the middle portion of the tendon, higher up from the heel, where the fibers break down, swell, and thicken. This type is more common in younger, active people. Both types tend to come on gradually and worsen with activity, especially running, climbing stairs, or pushing off during a sprint.
Heel Fat Pad Syndrome
Your heel bone sits on a specialized cushion of fat that absorbs shock with every step. Over time, this fat pad can thin out or become inflamed, leaving the bone with less protection against hard surfaces. The result is a deep, bruise-like ache in the center of your heel that gets worse the longer you’re on your feet.
Unlike plantar fasciitis, fat pad pain doesn’t follow the classic “worst in the morning, better after walking” pattern. It builds with activity and is especially noticeable when walking barefoot on hard floors like tile or concrete, or during high-impact sports like basketball and gymnastics. You can often reproduce the pain by pressing firmly into the middle of your heel pad.
Several things accelerate fat pad thinning. Repetitive pounding on hard surfaces wears down the tissue over time. Previous corticosteroid injections into the heel, sometimes given for other foot conditions, can cause the fat pad to shrink as a side effect. Repeated steroid injections further increase this risk. Age also plays a role, as the fat pad naturally loses elasticity and volume over the years.
Nerve Entrapment: A Commonly Missed Diagnosis
A small nerve that runs along the inside of your heel can become trapped or compressed, producing pain that’s easy to confuse with plantar fasciitis. This condition, sometimes called Baxter’s neuritis, has a distinctly different pain pattern that’s worth knowing about, especially if standard plantar fasciitis treatments aren’t helping.
The key difference is timing. Nerve entrapment pain does not produce that classic “first step” morning pain. Instead, it worsens with activity and builds as the day goes on. The location is also slightly different: rather than directly under the heel bone, the tenderness sits higher on the foot and more toward the inside. Many people with this condition also notice numbness along the inner heel or a burning sensation along the outer edge of the foot. In some cases, it even affects the ability to spread the fourth and fifth toes apart.
This distinction matters because stretching and orthotics, the go-to treatments for plantar fasciitis, won’t resolve a compressed nerve. If your heel pain doesn’t improve after several weeks of conservative care, or if you notice any numbness or burning, nerve involvement is worth investigating.
Heel Spurs: Rarely the Real Problem
If you’ve had an X-ray that showed a heel spur, it’s natural to assume that bony growth is stabbing you from the inside. But heel spurs are surprisingly common in people with zero pain. Roughly 11 to 16 percent of the general population has visible heel spurs on X-ray without any symptoms, and less than 5 percent of people with spurs actually experience pain from them. When heel pain and a spur appear together, the pain almost always comes from the surrounding soft tissue, not the spur itself. Treating the spur alone rarely solves the problem.
Heel Pain in Children
Kids between ages 8 and 14 who complain of heel pain, especially during or after sports, are very commonly dealing with a growth-related condition called Sever’s disease. During growth spurts, the heel bone’s growth plate is still open and vulnerable to repetitive pulling from the Achilles tendon. This creates inflammation at the back of the heel that flares up with running and jumping.
It’s not a serious condition and doesn’t cause long-term damage, but it can sideline an active child for weeks. Diagnosis is straightforward: a doctor applies gentle pressure to the heel and may ask the child to walk, run, or jump. Imaging is usually only ordered to rule out other problems. Rest, cushioned heel inserts, and calf stretching are typically enough to resolve it as the growth plate matures.
Stretches and Home Care That Help
For plantar fasciitis and many other forms of heel pain, consistent stretching is one of the most effective interventions. The key word is consistent. Doing stretches once a day won’t move the needle. Here’s what a structured routine looks like, based on protocols from Washington University Orthopedics:
- Standing calf stretch: Lean into a wall with one leg back, keeping the rear heel on the ground. Hold for 45 seconds, repeat 2 to 3 times, and do this 4 to 6 times throughout the day.
- Towel stretch: Loop a towel around the ball of your foot while seated and gently pull your toes toward you. Same protocol: 45-second holds, 2 to 3 reps, 4 to 6 sessions daily.
- Toe extension stretch: Pull your toes back toward your shin while seated, holding 10 seconds at a time for 2 to 3 minutes per session. Repeat 2 to 4 times per day.
- Frozen water bottle roll: Roll a frozen bottle under your arch for 3 to 5 minutes, twice daily. This combines a gentle stretch with icing to reduce inflammation.
Beyond stretching, supportive shoes with cushioned soles make a significant difference. Avoid walking barefoot on hard floors, particularly first thing in the morning. Over-the-counter arch supports or gel heel cups can reduce strain on the plantar fascia throughout the day.
When Home Care Isn’t Enough
Most heel pain improves within several weeks to a few months of consistent stretching, icing, and better footwear. If it doesn’t, imaging may be the next step. Clinical guidelines recommend weight-bearing X-rays as the first choice for chronic foot pain. If those come back normal but symptoms persist, an MRI or diagnostic ultrasound can reveal soft tissue problems like plantar fascia tears, nerve compression, or tendon damage that X-rays miss.
For stubborn cases, shockwave therapy is a non-invasive option that uses focused pressure waves to stimulate healing in the damaged tissue. It typically involves 3 sessions spaced a week or two apart, with success rates around 75 to 80 percent for heel pain. Custom orthotics, physical therapy, and in rare cases surgical release of the plantar fascia are additional options, but the vast majority of people recover without surgery.
