Heel pain most often comes from plantar fasciitis, a condition where the thick band of tissue running along the bottom of your foot becomes irritated or inflamed. But several other structures in and around the heel can generate pain, and the specific location, timing, and quality of your pain point toward different causes.
Plantar Fasciitis
The plantar fascia is a strong, stretchy band of tissue that connects your heel bone to the base of your toes. It supports your arch and absorbs shock every time you take a step. When this tissue is overused or stretched too far, small tears develop. Repeated tearing leads to irritation and swelling, though in many cases the exact trigger remains unclear. Roughly 1 in 120 adults in the United States are diagnosed with plantar fasciitis in a given year, making it by far the most common source of heel pain.
The hallmark symptom is a stabbing pain on the bottom of your foot, right near the heel. It’s usually worst with your first few steps in the morning or after sitting for a long time. The pain tends to ease once you walk around for a few minutes, then flare again after prolonged standing or when you get up from rest. Most people recover with conservative measures like stretching, supportive footwear, and reducing high-impact activity, though it can take several months to fully resolve.
Achilles Tendon Problems
Your Achilles tendon connects your calf muscles to the back of your heel bone, and it can develop pain in two distinct spots. Insertional tendinopathy affects the point where the tendon attaches to the heel. You’ll feel pain at the back of the heel, sometimes with visible swelling or a bony bump. Non-insertional tendinopathy, the more common form, causes pain a few inches above the heel in the middle portion of the tendon.
Both types typically come on gradually. You might notice a mild ache after running or climbing stairs that slowly worsens over weeks. Tightness in the calf muscles, a sudden increase in activity, or switching to shoes with a lower heel can all contribute. The key difference from plantar fasciitis is location: Achilles pain is at the back of the heel rather than the bottom.
Heel Stress Fractures
The calcaneus, your heel bone, can develop tiny cracks from repetitive impact. Unlike a sudden fracture from a fall, a stress fracture builds slowly. You might first notice a twinge in your heel that becomes more noticeable over days or weeks. The pain worsens when you put pressure on your heel, such as standing for a long time, and eases when you rest. Your heel may feel tender or warm to the touch, and bruising or stiffness can develop.
Stress fractures are more common in runners, military recruits, and anyone who rapidly increases their activity level. They can be tricky to diagnose because early X-rays often look normal. An MRI is typically needed to confirm the fracture and rule out soft tissue injuries. Recovery usually requires several weeks of reduced weight-bearing.
Heel Fat Pad Syndrome
A layer of fatty tissue sits beneath your heel bone, acting as a built-in shock absorber every time your foot hits the ground. Over time, this cushion can thin out or lose its elasticity, leaving the heel bone less protected from impact. The result is a deep, bruise-like ache in the center of the heel that worsens with barefoot walking or standing on hard surfaces.
Several factors accelerate fat pad breakdown:
- Age: The fat pad naturally loses volume and elasticity over the years.
- Hard surfaces: Walking or running barefoot on concrete or tile increases impact on the heel.
- Body weight: More weight means more pressure compressing the fat pad with every step.
- Repetitive pounding: High-impact sports or jobs that require prolonged standing wear the pad down faster.
- Unsupportive shoes: Flat shoes or worn-out soles force the heel to absorb more shock than it should.
Fat pad pain can feel similar to plantar fasciitis, but it’s centered more directly under the heel bone rather than toward the front of the heel. It also doesn’t follow the same “worst with the first morning steps” pattern as clearly.
Nerve Compression
A condition called tarsal tunnel syndrome occurs when the tibial nerve, which runs along the inside of the ankle into the foot, gets compressed or pinched. The symptoms feel distinctly different from muscle or bone injuries. Instead of a sharp or aching pain, you’re more likely to notice burning, tingling, numbness, or a “pins and needles” sensation in the bottom of your foot or the inside of your ankle. Some people also feel weakness in the foot.
Anything that crowds the space around the nerve can trigger it: swelling from an ankle sprain, flat feet that stretch the nerve, a cyst, or varicose veins near the ankle. The sensation often worsens with standing or walking and improves with rest. If your heel pain comes with tingling or numbness, nerve involvement is worth investigating.
Inflammatory Conditions
Systemic inflammatory diseases can target the heel. Rheumatoid arthritis affects the joints and tendons of the hindfoot, sometimes tightening the Achilles tendon and shifting the alignment of foot bones. Early on, you might notice difficulty walking on uneven ground. Over time, the arch can flatten as tendons weaken and bones shift out of position.
Gout is another possibility. It most famously strikes the big toe, but uric acid crystals can deposit in the heel as well, causing sudden, intense pain and swelling. Ankylosing spondylitis, a type of inflammatory arthritis that primarily affects the spine, frequently causes pain where tendons attach to the heel bone. If your heel pain is accompanied by joint pain elsewhere in your body, morning stiffness lasting more than 30 minutes, or episodes of sudden swelling, an inflammatory condition may be driving it.
Heel Pain in Children
Kids and teenagers can develop a specific type of heel pain called calcaneal apophysitis, commonly known as Sever’s disease. The heel bone is one of the first parts of the body to reach full size during a growth spurt. Because the bone grows faster than the surrounding muscles and tendons, the Achilles tendon pulls tightly on the heel’s growth plate, causing pain at the back of the heel.
It typically shows up in girls around ages 8 to 10 and in boys between 10 and 12. Active kids who play sports with lots of running and jumping are most affected. By around age 15, the growth plate hardens into solid bone and the condition resolves on its own. In the meantime, reducing high-impact activity, stretching the calves, and using cushioned heel inserts can keep the pain manageable.
How to Tell Your Causes Apart
The location and timing of your pain are the most useful clues:
- Bottom of the heel, worst in the morning: Plantar fasciitis is the most likely cause.
- Center of the heel, worse on hard surfaces: Fat pad thinning.
- Back of the heel: Achilles tendon problems or, in children, Sever’s disease.
- Gradual onset that worsens with activity, eases with rest: Possible stress fracture.
- Burning, tingling, or numbness: Nerve compression.
- Sudden intense swelling or pain in multiple joints: An inflammatory condition.
Footwear and Daily Habits That Help
Regardless of the specific cause, what you put on your feet matters. Shoes that help with heel pain share a few features: firm arch support to distribute pressure across the foot rather than concentrating it on the heel, ample cushioning in the heel area to absorb shock, and a solid heel counter (the rigid part at the back of the shoe) to stabilize the foot. The shoe should flex enough for natural movement but not so much that it offers no structure. Flat shoes like ballet flats and flip-flops provide almost no support, and high heels shift weight forward in ways that stress the heel and Achilles tendon. Both are worth avoiding when you’re dealing with heel pain.
Beyond footwear, calf stretching helps with most causes of heel pain because tight calves increase tension on both the Achilles tendon and the plantar fascia. Rolling a frozen water bottle under the arch of your foot can reduce inflammation and loosen tight tissue. If your pain doesn’t improve after two to three weeks of rest, better shoes, and consistent stretching, imaging may be needed to rule out fractures or other structural problems.
