The most common reason your heels hurt is plantar fasciitis, a condition where the thick band of connective tissue running along the bottom of your foot becomes inflamed or develops small tears. But heel pain has several possible causes, and where exactly you feel the pain, when it’s worst, and how it started all point toward different answers.
Plantar Fasciitis: The Most Likely Cause
Plantar fasciitis accounts for more cases of heel pain than any other condition. The connective tissue along the sole of your foot (the plantar fascia) stretches, tears, or becomes inflamed, typically from repetitive impact. Running, jumping, and spending long hours on hard surfaces like concrete are the most common triggers. Treadmills are another frequent culprit.
The hallmark symptom is a stabbing pain on the bottom of your heel, usually worst with your first steps in the morning or after sitting for a while. It often eases once you’ve been moving for a few minutes, then returns after extended time on your feet. Most people recover within several months using conservative approaches: icing the area, stretching the calf and foot, and reducing or modifying the activities that caused it.
Left untreated over time, chronic plantar fasciitis can lead to a heel spur, a bony growth on the heel bone. Heel spurs themselves don’t always cause pain, but they signal that the underlying fascia has been irritated for a long time.
Fat Pad Syndrome: Often Mistaken for Plantar Fasciitis
Your heel has a natural cushion of fat that absorbs shock when you walk. When this padding thins out or loses its elasticity, each step sends more force directly into the bone. Fat pad syndrome is considered the second leading cause of heel pain on the bottom of the foot, and it’s frequently misdiagnosed as plantar fasciitis.
The pain feels like a deep bruise in the center of your heel. It gets worse when you stand or walk for long stretches, during high-impact activities like running or jumping, and especially when you walk barefoot on hard surfaces like hardwood floors or tile. In mild cases, you may only notice it occasionally.
One way to tell it apart from plantar fasciitis: fat pad pain is typically right in the middle of the heel and can be reproduced by pressing firmly into that spot. Plantar fasciitis pain tends to concentrate closer to the front of the heel, where the fascia attaches. A healthy heel pad measures roughly 1 to 2 centimeters thick. Your doctor can compare the thickness when you’re standing versus sitting to check for abnormal compression or stiffness.
Pain at the Back of the Heel
If your pain is at the back of the heel rather than the bottom, the cause is likely different. Achilles tendinitis is an overuse injury of the thick tendon connecting your calf muscle to your heel bone. It’s especially common in runners and basketball players. You’ll notice pain, swelling, and stiffness at the back of the heel, often after increasing your activity level too quickly.
Bursitis is another back-of-heel condition. Small fluid-filled sacs that cushion the joint become swollen and inflamed, producing a tender, bruise-like feeling. It typically develops after spending a lot of time on your feet.
A third possibility is Haglund’s deformity, sometimes called a “pump bump.” Chronic irritation causes an enlarged bony bump to form at the back of the heel. Shoes with rigid heel counters or higher heels tend to make it worse by pressing directly against the bump.
Nerve Entrapment
Sometimes heel pain comes from a pinched nerve rather than a structural problem. A small nerve near the inner heel can become compressed as it passes through tight tissue in the arch of the foot. This produces a sharp, radiating pain along the inside of the heel that often worsens at night and after physical activity like walking. Some people also notice tingling or unusual sensations spreading outward from the tender spot. This type of heel pain is less common, but it’s worth considering if your pain doesn’t follow the typical pattern of plantar fasciitis and hasn’t responded to standard stretching and rest.
Bone Bruises and Stress Fractures
Stepping on a hard or sharp object can bruise the fat padding underneath your heel. You may not see any discoloration, but the heel feels tender when you walk and sometimes even at rest. These bruises generally heal on their own with time and reduced activity.
A stress fracture of the heel bone is more serious. Unlike a bruise that stays in one spot, stress fracture pain often spreads along the bottom, side, and back of the heel. A simple clinical test involves squeezing both sides of the heel simultaneously. If that squeeze reproduces your pain, it raises suspicion for a fracture and warrants imaging. Stress fractures typically develop from repetitive overloading, like a sudden increase in running mileage or training on hard surfaces without adequate recovery.
Heel Pain in Children
If your child is complaining of heel pain, the most likely cause is Sever’s disease, which is an irritation of the growth plate in the back of the heel. It’s common in active kids between the ages of 8 and 14, especially those who do a lot of running and jumping. Despite its name, it’s not a disease. It’s a temporary overuse condition that resolves once the growth plate fully matures.
What Helps Heel Pain at Home
Regardless of the specific cause, a few strategies help most types of heel pain. Reducing or temporarily stopping the activity that triggered it gives the tissue time to heal. Icing the painful area for 15 to 20 minutes helps control inflammation. Stretching your calves and the bottom of your foot (rolling your arch over a frozen water bottle is a popular method) loosens the structures that pull on the heel.
Footwear matters more than most people realize. Shoes that help heel pain share a few key features: a stable base with a firm heel counter to prevent wobble, adequate cushioning that absorbs impact without bottoming out, and a heel-to-toe drop of roughly 8 to 12 millimeters, which reduces the load on your heel when it strikes the ground. Removable insoles are useful because they leave room for custom orthotics or heel cups if you need them. Avoid shoes that are flat, unsupportive, or too narrow. Walking barefoot on hard surfaces is one of the worst things you can do while your heel is healing.
Signs Your Heel Pain Needs Attention
Most heel pain improves with rest, stretching, and better shoes. But certain patterns suggest something more is going on. Pain that persists for more than a few weeks despite home care, heel pain that’s severe enough to change how you walk, numbness or tingling in the foot, swelling that doesn’t resolve, or pain that came on suddenly during activity (which could signal an Achilles tendon tear) all warrant a professional evaluation. Imaging with X-ray, ultrasound, or MRI can help distinguish between conditions that look similar on the surface but require different treatment approaches.
