The most common reason your heel hurts is plantar fasciitis, a condition where the thick band of tissue running along the bottom of your foot becomes irritated from repeated stress. But heel pain can come from several different structures depending on exactly where it hurts, what makes it worse, and how the pain feels. The location and timing of your pain are the best clues to narrowing down the cause.
Plantar Fasciitis: Pain on the Bottom of Your Heel
A tough band of tissue called the plantar fascia connects your heel bone to the base of your toes. It supports your arch and absorbs shock every time you take a step. When that tissue gets overloaded, small tears develop, leading to irritation and a stabbing pain near the bottom of the heel.
The hallmark sign is pain with your first few steps in the morning. While you sleep, the fascia tightens in a shortened position. When you stand up and stretch it under your full body weight, those damaged fibers protest. The pain typically eases as you walk around and the tissue warms up, then returns after long periods of sitting or standing. If this pattern sounds familiar, plantar fasciitis is the most likely explanation.
Risk factors include spending long hours on your feet, a recent increase in activity, tight calf muscles, higher body weight, and shoes with poor arch support. It can affect one foot or both.
Achilles Tendonitis: Pain at the Back of Your Heel
If the pain is behind your heel rather than underneath it, the Achilles tendon is the more likely culprit. This tendon connects your calf muscles to your heel bone, and it can become inflamed either in its midsection or right where it attaches to the bone. The attachment point version, called insertional Achilles tendonitis, is the one that feels like heel pain specifically.
It usually starts as a mild ache after running, climbing stairs, or other activity, then gradually worsens. Over time, you may notice pain even at rest. A bony bump at the back of the heel can develop alongside it. The key distinction from plantar fasciitis is location: back of the heel versus bottom of the heel.
Heel Fat Pad Syndrome: A Bruised, Achy Feeling
Your heel bone sits on a cushion of fatty tissue that acts as a natural shock absorber. Over time, this fat pad can thin out or lose its elasticity, leaving the bone less protected from impact. The result is a deep, bruise-like ache that gets worse the longer you’re on your feet.
Several things accelerate fat pad thinning. Age is the biggest factor, as the tissue naturally loses volume over the years. Walking or running barefoot on hard surfaces like concrete, wearing shoes without adequate cushioning, and spending long hours standing all contribute. Unlike plantar fasciitis, fat pad pain tends to feel centered directly under the heel bone and doesn’t have the same dramatic “first step in the morning” pattern, though it can overlap.
Stress Fracture of the Heel Bone
A stress fracture is a tiny crack in your heel bone that develops gradually from repetitive impact. It’s less common than soft tissue causes, but it’s important to recognize because it requires a different approach. The pain builds over days or weeks, starting as a minor twinge and becoming increasingly hard to ignore. It gets worse when you put weight on the heel, especially with prolonged standing, and eases when you’re off your feet.
Other signs include bruising, stiffness, tenderness when you press on the sides of your heel, and warmth to the touch. Stress fractures are more likely if you’ve recently ramped up your activity level, switched to harder training surfaces, or have low bone density.
Nerve Compression: Burning or Tingling Pain
When heel pain comes with burning, tingling, numbness, or a “pins and needles” sensation, a compressed nerve may be involved. Tarsal tunnel syndrome occurs when the nerve running along the inside of your ankle gets squeezed as it passes through a narrow bony channel. The pain often radiates to the bottom of the foot and can include weakness in the foot muscles.
Nerve-related heel pain typically worsens during or after physical activity. In more severe cases, the tingling and burning can become constant. The neurological quality of the pain, that electric or buzzing feeling, is what sets it apart from the duller ache of fascia or bone problems.
Heel Spurs Are Rarely the Problem
Many people assume a heel spur is causing their pain, but research tells a different story. Between 11% and 16% of the general population has a visible heel spur on X-ray with absolutely no symptoms. A spur is a bony growth that forms in response to chronic pulling on the heel bone, often from the same stress that causes plantar fasciitis. It’s a sign of long-term strain, not the source of pain itself. Treating the underlying soft tissue problem, not the spur, is what brings relief.
Using Pain Location to Identify the Cause
- Bottom of the heel, worst in the morning: plantar fasciitis
- Back of the heel, worse after activity: Achilles tendonitis
- Deep ache directly under the heel, worse with standing: fat pad atrophy
- Gradual onset with bruising and tenderness on both sides of the heel: stress fracture
- Burning, tingling, or numbness: nerve compression
What Helps Heel Pain
For plantar fasciitis, which accounts for the majority of cases, the strongest evidence supports a combination of stretching, hands-on therapy, and taping. Stretching both the plantar fascia itself (by pulling your toes back toward your shin) and your calf muscles has the highest grade of evidence for both short-term and long-term pain reduction. If your pain is worst with the first step in the morning, a night splint worn for one to three months can keep the fascia gently stretched while you sleep, reducing that initial jolt of pain.
Foot taping, using either rigid athletic tape or elastic kinesiology tape, provides short-term relief when combined with other treatments. Strengthening exercises for the muscles of the foot and ankle also help, particularly for preventing recurrence. Insoles and orthotics work best as part of a broader plan rather than a standalone fix. Custom orthotics are not necessarily better than good prefabricated ones for most people.
Shoes That Reduce Heel Strain
The right footwear can make a meaningful difference. Look for shoes with a firm heel counter (the rigid part that wraps the back of your heel) to minimize wobble, a heel-to-toe drop of roughly 8 to 12 millimeters to reduce load on the heel during each step, and cushioning that absorbs impact without feeling mushy. A rocker-style sole, where the shoe curves slightly upward at the toe and heel, reduces the braking force at heel strike and distributes pressure more evenly as you roll through each step.
Removable insoles are a practical feature because they let you swap in a custom orthotic or heel cup if needed. A roomy toe box also matters: a shoe that squeezes the front of your foot can change your gait and increase strain further back.
Warning Signs That Need Prompt Attention
Most heel pain responds to conservative care over a few weeks. But certain patterns warrant faster evaluation. Severe pain and swelling immediately after an injury, inability to bend your foot downward or stand on your toes, and heel pain accompanied by fever or numbness all call for prompt medical attention. Pain that persists at rest, including pain that wakes you at night, or heel pain lasting more than a few weeks despite rest and home care, is also worth getting checked.
