The most likely reason your heel hurts is plantar fasciitis, a condition that affects roughly 10% of adults at some point in their lives. It happens when the thick band of tissue running along the bottom of your foot becomes irritated and inflamed from repeated stress. But the bottom of the heel isn’t the only spot that flares up, and plantar fasciitis isn’t the only possibility. Where exactly you feel the pain, when it’s worst, and how it started all point toward different causes.
Pain on the Bottom of the Heel
Plantar fasciitis is by far the most common culprit when the bottom of your heel hurts. Every time your heel strikes the ground, the plantar fascia absorbs force and distributes it across your foot. Over time, that repeated loading creates tiny tears in the tissue where it attaches to the heel bone. Your body responds with inflammation, and the result is a sharp or aching pain right at the base of the heel.
The hallmark symptom is pain with your first steps in the morning. While you sleep, the inflamed tissue tightens and contracts. When you stand up and put weight on it, those first few steps stretch it abruptly, which is why the pain can be intense for a few minutes and then gradually ease as you move around. The same thing happens after sitting for a long time at your desk or in a car. You might also notice it flaring after exercise rather than during it.
Heel spurs often show up on X-rays alongside plantar fasciitis, which has led to a persistent misunderstanding. A heel spur is a small bony growth on the heel bone that can develop from long-term tension on the plantar fascia. But spurs themselves are not what’s causing your pain. Most people who have heel spurs on imaging have no heel pain at all, and plantar fasciitis is successfully treated without ever addressing the spur.
Pain at the Back of the Heel
If the pain is behind or above your heel rather than underneath it, the Achilles tendon is the more likely source. This is the thick cord connecting your calf muscles to your heel bone, and it can become inflamed from overuse, sudden increases in activity, or tight calves.
There are two forms. Insertional Achilles tendonitis affects the spot where the tendon meets the heel bone and can produce bone spurs at that junction. Noninsertional tendonitis involves small tears in the middle portion of the tendon itself. Both cause stiffness and soreness that’s worst when you first get up, pain that worsens with activity throughout the day, and sometimes visible swelling or thickening of the tendon. You might also notice difficulty flexing your foot upward. A sudden pop with sharp pain is a more serious sign that the tendon may have ruptured, which needs immediate attention.
Deep, Bruise-Like Heel Pain
If the pain feels less like a sharp stab and more like a deep bruise in the center of your heel, the problem may be your heel’s fat pad. The bottom of your heel has a built-in cushion of fatty tissue that acts as a shock absorber every time your foot hits the ground. Over time, this pad can thin out or lose its elasticity, leaving the heel bone with less protection against impact.
This condition is more common as you age, since the fat pad naturally shrinks over the years. Carrying extra body weight accelerates the process by increasing pressure on the pad with every step. The pain tends to be worst when you walk barefoot on hard surfaces like tile or concrete, stand for long stretches, or do high-impact activities like running or jumping. Unlike plantar fasciitis, this pain doesn’t have the same dramatic “first step” pattern in the morning. It’s more consistent and tied directly to how much impact your heel is absorbing.
Less Common but Worth Knowing
A calcaneal stress fracture can mimic the symptoms of soft tissue problems but requires different treatment. Stress fractures develop from cumulative overload, often in runners or people who suddenly increase their activity. The pain typically gets worse with any weight-bearing activity and doesn’t improve with the usual stretches and rest that help plantar fasciitis. Diagnosis usually requires an MRI, since stress fractures often don’t show up on standard X-rays early on.
Nerve issues can also cause heel pain. Compression of the nerve that runs along the inside of the ankle (sometimes called tarsal tunnel syndrome) can create burning, tingling, or numbness in the heel. If your pain comes with unusual sensations rather than a straightforward ache, that’s a clue the nerve may be involved.
What Actually Helps
Most heel pain from plantar fasciitis resolves within several months using straightforward, at-home approaches. The key is consistency rather than intensity.
Stretching is the single most effective thing you can do. Three stretches cover the basics:
- Seated arch stretch: While sitting, grab your toes and gently pull them toward you until you feel a stretch along the arch of your foot.
- Calf stretch: Stand facing a wall with your back leg straight and heel flat on the floor. Lean your hips forward until you feel the stretch in your calf. Repeat on both sides.
- Towel curls: Place a towel on the floor and use your toes to scrunch it toward you. This strengthens the small muscles supporting your arch.
Hold each stretch for at least 30 seconds without bouncing, and do one or two repetitions, two to three times a day. Morning stretches before your first steps can make a noticeable difference in that initial burst of pain.
Icing the sore area for 15 to 20 minutes after activity helps control inflammation. Reducing or temporarily modifying the activities that triggered the problem (long runs, extended standing, worn-out shoes) gives the tissue time to heal. Supportive shoes with good arch support and cushioned heels take strain off the fascia throughout the day. Night splints, which hold your foot at a 90-degree angle while you sleep, prevent the fascia from tightening overnight and can reduce that painful morning stiffness.
For fat pad atrophy, the strategy shifts toward maximizing cushioning. Gel heel cups, well-padded shoes, and avoiding barefoot walking on hard floors are the main tools. Stretching alone won’t restore lost fat pad tissue.
When Conservative Treatment Isn’t Enough
If your heel pain persists beyond a few months of consistent stretching, icing, and activity modification, there are next-level options. Shockwave therapy, which uses sound wave pulses directed at the painful area, has a success rate of roughly 60 to 80% for plantar fasciitis and typically involves a short series of sessions. Custom orthotics can correct biomechanical issues that keep re-stressing the fascia. Physical therapy adds targeted strengthening to address underlying weaknesses in the foot, ankle, or calf.
Surgery is rare and reserved for cases that don’t respond to anything else after 6 to 12 months.
Signs That Need Prompt Attention
Most heel pain is frustrating but not dangerous. However, certain symptoms warrant a prompt visit: severe pain and swelling right after an injury, inability to bend your foot downward or rise onto your toes, inability to walk normally, or heel pain accompanied by fever, numbness, or tingling. These patterns can indicate a fracture, ruptured tendon, or nerve damage that requires more urgent evaluation.
