Heel pain when you put pressure on it is most commonly caused by plantar fasciitis, an irritation of the thick band of tissue that runs along the bottom of your foot. But several other conditions produce similar symptoms, and where exactly the pain hits, when it’s worst, and what it feels like can help you narrow down what’s going on.
Plantar Fasciitis: The Most Common Cause
The plantar fascia is a tough strip of connective tissue that connects your heel bone to the base of your toes, acting like a built-in shock absorber. When this tissue is repeatedly stretched and stressed, small tears develop. Over time, that cycle of tearing and attempted healing leads to inflammation and pain concentrated right where the fascia attaches to the heel bone.
The hallmark symptom is stabbing pain with your first steps in the morning. After sitting or sleeping, the fascia tightens up. When you stand, that sudden stretch on already-irritated tissue produces a sharp jolt in the bottom of your heel. The pain often eases after a few minutes of walking as the tissue loosens, then returns after long periods on your feet or when you stand up after resting.
Risk factors include spending most of your day standing or walking, carrying extra body weight, tight calf muscles, and suddenly increasing your activity level. Runners and people who wear flat, unsupportive shoes are particularly prone. The pain is usually worst directly in front of the heel bone on the underside of the foot, not in the center or back of the heel.
Heel Fat Pad Syndrome
Your heel has a built-in cushion: a specialized pad of fat that absorbs impact every time your foot hits the ground. When this pad thins out or loses its elasticity, the heel bone sits closer to the surface and takes a beating with every step. This is the second leading cause of plantar heel pain, and it’s frequently misdiagnosed as plantar fasciitis.
The key difference is what the pain feels like and where it sits. Fat pad syndrome produces a deep, bruise-like ache right in the center of the heel, as if you’re walking on a stone. You can often reproduce the pain by pressing firmly into the middle of the heel with your thumb. It gets worse when you walk barefoot on hard surfaces like tile or concrete, during high-impact activities like jumping or running, and after long stretches of standing. Unlike plantar fasciitis, it doesn’t typically produce that dramatic first-step-of-the-morning pain.
Fat pad atrophy happens naturally with age, but it can also result from years of high-impact activity, repeated steroid injections to the heel, or simply wearing thin-soled shoes on hard surfaces for decades.
Stress Fractures in the Heel Bone
A stress fracture in the calcaneus (your heel bone) is a small, incomplete crack caused by repetitive force rather than a single injury. This is more common than many people realize, especially in runners, military recruits, and anyone who dramatically ramps up their activity level.
The pain tends to build gradually over days or weeks. A useful self-check: squeeze both sides of your heel (the inner and outer surfaces) with your hand. If that squeeze reproduces or worsens the pain, a stress fracture is a real possibility. Another telling sign is inability to hop on that foot without significant pain. You may also notice mild swelling or bruising around the heel.
Stress fractures won’t improve with stretching or orthotics alone. They require a period of reduced weight-bearing to heal properly, so persistent heel pain that worsens with activity and doesn’t follow the typical plantar fasciitis pattern warrants imaging.
Pain at the Back of the Heel
If your pain is behind the heel rather than underneath it, the likely culprits are different. Heel bursitis involves inflammation of small fluid-filled sacs near the Achilles tendon. The more common type, retrocalcaneal bursitis, affects the bursa tucked between your heel bone and Achilles tendon. A less common form involves the bursa between the skin and the tendon itself, often aggravated by stiff shoe backs that press into the heel.
Both types produce pain, swelling, and tenderness at the back of the ankle near the heel. The pain typically worsens when you push off during walking or go up on your toes. Tight or rigid shoes that dig into the back of the heel are a frequent trigger.
Nerve-Related Heel Pain
Tarsal tunnel syndrome occurs when the tibial nerve, which runs along the inside of your ankle, becomes compressed or damaged. This condition produces a distinctly different quality of pain compared to fasciitis or fat pad problems. Instead of a deep ache or sharp stab, you’ll notice burning, tingling, numbness, or a “pins and needles” sensation in the bottom of the foot or inside of the ankle. Some people also develop weakness in the foot muscles over time.
Nerve pain often doesn’t follow a predictable pattern tied to activity. It can flare at rest, worsen at night, or radiate from the ankle down into the foot. If your heel pain comes with any electric, burning, or tingling quality, nerve involvement is worth investigating.
Heel Pain in Children and Teens
In growing kids, the most common cause of heel pain is Sever’s disease (calcaneal apophysitis). This isn’t actually a disease. It’s an overuse condition affecting the growth plate in the heel bone. During growth spurts, bones lengthen faster than the muscles and tendons can keep up, creating extra tension at the heel where the Achilles tendon attaches.
Children and adolescents who play running and jumping sports are at the highest risk. The pain is brought on by activity and improves with rest. It typically resolves on its own once the growth plate matures and closes, but managing activity levels and using supportive footwear in the meantime can make a significant difference in comfort.
What Helps With Pressure-Related Heel Pain
For most cases of heel pain, the first line of relief is reducing the load on the heel. Stretching the calf and the plantar fascia itself (pulling your toes back toward your shin for 30 seconds, several times a day) helps with fasciitis in particular. Rolling a frozen water bottle under the foot combines stretching with inflammation control.
Shoe inserts are widely used, but the type matters less than you might expect. One well-known clinical study compared silicone heel pads, felt pads, rubber heel cups, and custom orthotics for plantar fasciitis and found that all groups improved, with no significant difference in overall pain reduction after eight weeks when each was paired with stretching. However, a separate study found that custom orthotics designed to control foot mechanics led to improvement in 70% of patients, compared to only 30% for cushioned heel cups alone. The takeaway: simple cushioning helps in the short term, but if your pain persists, an orthotic that addresses how your foot moves may be more effective than one that just adds padding.
For fat pad syndrome specifically, gel heel cups and well-cushioned shoes with thick midsoles can compensate for the lost natural cushion. Avoiding going barefoot on hard floors is one of the simplest changes you can make.
Signs That Need Prompt Attention
Most heel pain improves within weeks to a few months with consistent self-care. But certain patterns warrant medical evaluation sooner. Heel pain that wakes you up at night (not just hurts when you first get up) can signal infection, a bone abnormality, or neuropathy. Significant swelling, bruising, or inability to bear weight at all suggests a possible fracture. Numbness, tingling, or a burning quality points toward nerve involvement that benefits from early diagnosis. And heel pain in a person with diabetes needs careful evaluation because of the risk of Charcot arthropathy, a serious condition where weakened bones in the foot can collapse without proper management.
