The most likely reason your heel hurts is plantar fasciitis, which accounts for the vast majority of heel pain cases. But “heel pain” isn’t one condition. Where exactly it hurts, when it hurts, and what the pain feels like all point to different causes, some minor and some worth getting checked out. The good news: over 80% of people with the most common types of heel pain recover fully within 12 months using simple, non-surgical approaches.
Plantar Fasciitis: The Most Common Cause
Plantar fasciitis is pain along the thick band of tissue that runs from your heel bone to your toes. The hallmark symptom is a throbbing pain on the bottom of your heel, slightly toward the inner side, that’s worst with your first steps in the morning or after sitting for a while. It typically eases up after you’ve walked around for a few minutes, then returns if you’re on your feet too long.
Despite the name (which implies inflammation), the condition is actually more of a wear-and-tear problem. The tissue shows signs of degeneration rather than classic inflammation: disorganized collagen fibers, thickening, and poor blood flow. That reduced blood supply makes it harder for the tissue to repair itself, which is why it can linger for months. Risk factors include sudden increases in activity, spending long hours on your feet, tight calf muscles, higher body weight, and flat feet or very high arches.
If you press firmly on the inner part of your heel bone or along the arch, you’ll feel a sharp, stabbing pain. That’s a fairly reliable self-check. The pain is usually on the bottom of the foot, not the back of the heel.
Heel Fat Pad Syndrome
Your heel has a built-in cushion: a pad of fatty tissue that absorbs shock every time your foot hits the ground. When that pad thins out or loses elasticity, you get a deep, bruise-like pain right in the center of your heel. It feels different from plantar fasciitis. The pain is more directly under the heel rather than toward the inner side, and it doesn’t follow that classic “worst with first morning steps” pattern.
This condition is more common as you age, since the fat pad naturally loses volume over time. It’s also triggered by walking barefoot on hard floors (tile, concrete, hardwood), high-impact sports like basketball or running, and carrying extra body weight. If you press your thumb firmly into the middle of your heel and reproduce that deep, bruise-like pain, fat pad syndrome is a likely culprit. People with rheumatoid arthritis or lupus have a higher risk, as do those who’ve had corticosteroid injections in the heel for other foot problems.
Achilles Tendon Problems
If your pain is at the back of your heel rather than the bottom, the Achilles tendon is the prime suspect. This tendon connects your calf muscles to your heel bone, and it can break down in two distinct spots.
Insertional Achilles tendonitis causes pain right where the tendon attaches to the heel bone, at the lower back of your heel. You might feel a bony bump there. Mid-portion tendonitis hits higher up, in the middle of the tendon a few inches above the heel. Both types produce an achy pain that worsens with activity, and you’ll feel increased pain if you pull your toes up toward your shin, which stretches the tendon. The area may feel tender and thickened when you pinch it.
Achilles problems commonly show up after ramping up exercise too quickly, especially running or hill workouts. They can also be linked to inflammatory conditions like ankylosing spondylitis or psoriatic arthritis, particularly when the pain is right at the insertion point.
Stress Fractures
A calcaneal stress fracture is a small crack in the heel bone itself. Unlike soft tissue injuries, this pain tends to develop gradually over days to weeks, usually after a significant increase in weight-bearing activity or a switch to harder walking or running surfaces. Early on, the pain only shows up during activity. As the fracture worsens, it starts hurting at rest too.
The key distinguishing test: if squeezing both sides of your heel (not pressing the bottom) reproduces the pain, that points toward a stress fracture rather than a soft tissue problem. You might also notice some swelling or bruising. Runners and people who do a lot of jumping are at higher risk. Diagnosis typically requires an MRI or bone scan, since stress fractures often don’t show up on regular X-rays early on.
Nerve-Related Heel Pain
If your heel pain comes with burning, tingling, or numbness, a nerve problem may be involved. One common culprit is entrapment of a small nerve branch on the inner side of the heel (sometimes called Baxter’s nerve). This causes pain along the inner heel that can radiate outward, sometimes accompanied by an odd tingling sensation. It’s frequently misdiagnosed as plantar fasciitis because the pain location overlaps, but the burning or electric quality of the pain is the giveaway.
Pressing on the inner side of the heel near the arch muscle can trigger the pain and may reproduce that radiating discomfort. Neuromas, which are thickened areas of nerve tissue, can also develop in the heel area. You might feel a small painful lump when pressing the affected spot.
How to Tell These Apart
- Bottom of heel, inner side, worst in the morning: plantar fasciitis
- Dead center of heel, deep bruise feeling: heel fat pad syndrome
- Back of heel, worse with activity: Achilles tendon problem
- Pain when squeezing sides of heel: possible stress fracture
- Burning, tingling, or numbness: nerve entrapment
What Helps Heel Pain Resolve
For plantar fasciitis and most soft tissue causes, the foundation of treatment is the same: relative rest (cutting back on the activity that triggered it), stretching the calf and plantar fascia, supportive footwear, and over-the-counter arch supports or heel cups. Rolling a frozen water bottle under your foot for 10 to 15 minutes can help with pain. Avoiding walking barefoot, especially on hard surfaces, matters for both plantar fasciitis and fat pad syndrome.
Calf stretches are particularly effective because tight calves increase strain on the plantar fascia. Hold a wall stretch for 30 seconds, three times per leg, several times a day. Night splints, which keep your foot flexed while you sleep, can reduce that intense morning pain by preventing the fascia from tightening overnight.
For fat pad syndrome specifically, cushioned heel inserts and well-padded shoes make the biggest difference since you’re essentially replacing lost natural cushioning. Achilles tendon problems respond well to eccentric exercises, where you slowly lower your heel off the edge of a step. Stress fractures require a different approach entirely: offloading the heel with a walking boot or crutches for several weeks.
Most people see significant improvement within two to three months of consistent self-care. The 80% resolution rate within 12 months applies to plantar fasciitis treated conservatively, and most other soft tissue causes follow a similar timeline. Surgery is rarely needed.
Signs That Need Prompt Attention
Heel pain that developed after a fall, a hard landing, or a sudden twist warrants an evaluation to rule out a fracture. Pain that worsens steadily despite weeks of rest, pain that keeps you awake at night, or visible swelling and bruising also deserve a closer look. If you have heel pain alongside joint pain or stiffness in your lower back, hips, or other joints, that pattern can signal an inflammatory condition like ankylosing spondylitis or psoriatic arthritis, which requires different treatment. Numbness, tingling, or weakness in the foot that doesn’t resolve within a few days should also be evaluated.
