Heel pain most commonly comes from plantar fasciitis, an inflammation of the thick band of tissue running along the bottom of your foot. But the heel is a surprisingly complex structure, and where exactly it hurts, when it hurts, and how it hurts all point to different causes. Understanding those differences helps you figure out what’s going on and what to do about it.
Pain on the Bottom of the Heel
The most likely culprit for pain under your heel is plantar fasciitis. The plantar fascia is a tough strip of connective tissue that runs from your heel bone to the base of your toes, supporting your arch with every step. When it’s overused or overstretched, it becomes inflamed and swollen, making weight-bearing painful.
The hallmark sign is throbbing pain with your first steps in the morning or after sitting for a while. Those first few steps feel sharp and stabbing, then the pain fades as you move around. It often returns later in the day after prolonged standing or walking. If that pattern sounds familiar, plantar fasciitis is the most probable explanation.
Two other conditions cause pain in a similar location but feel different. Heel pad syndrome produces a deep, bruise-like ache right in the center of the heel rather than near the inner edge. It gets worse when you walk barefoot on hard floors or stand for long stretches. The heel’s natural fat cushion loses elasticity with age, so this condition is more common in older adults. You can sometimes feel the difference: the heel pad feels stiff and thin rather than springy.
A calcaneal stress fracture is the third possibility. Unlike plantar fasciitis, the pain from a stress fracture gets worse the more you move and improves when you stop. Swelling around the heel is another distinguishing clue. A simple squeeze test can help: if pressing the sides of your heel bone between your thumb and fingers reproduces sharp pain, that pattern fits a stress fracture more than soft tissue inflammation. Stress fractures typically follow a sudden increase in activity or a switch to harder walking or running surfaces.
Pain at the Back of the Heel
If the pain is behind your heel rather than underneath it, the Achilles tendon is the usual suspect. Achilles tendinopathy causes an achy pain that occasionally turns sharp, especially with increased activity or direct pressure on the tendon. You may notice the tendon looks thicker than normal or feel a firm bump along it. Flexing your foot upward stretches the tendon and typically makes the pain worse.
Retrocalcaneal bursitis is a related condition affecting a small fluid-filled sac between the Achilles tendon and the heel bone. It causes redness and visible swelling right at the back of the heel, and the area is tender when pressed directly. A bony bump on the back of the heel, sometimes called a “pump bump,” can contribute to this irritation by pressing against shoes.
Burning, Tingling, or Numbness
When heel pain comes with burning, tingling, or pins-and-needles sensations, a nerve is likely involved. Tarsal tunnel syndrome occurs when the tibial nerve gets compressed as it passes through a narrow channel on the inner side of the ankle. The pain and tingling typically spread to the bottom of the foot. Symptoms tend to worsen during or after physical activity, and in more severe cases they can become constant. Weakness in the small muscles of the foot is another sign that a nerve is being compressed rather than a tendon or bone being injured.
What About Heel Spurs?
Many people assume a bony heel spur is causing their pain, but the relationship is less straightforward than it seems. Heel spurs are calcium deposits that form on the underside of the heel bone, and they show up on X-rays in a surprisingly large portion of people who have no pain at all. Studies have found asymptomatic heel spurs in anywhere from 11 to 63 percent of the general population, depending on how the research was conducted. A spur on an X-ray doesn’t necessarily explain your symptoms. In most cases, the pain attributed to a “heel spur” is actually coming from the inflamed plantar fascia or surrounding soft tissue, not from the bony growth itself.
Heel Pain in Kids and Teens
Children and adolescents get heel pain for a different reason. Sever’s disease (calcaneal apophysitis) occurs during growth spurts, when the heel bone grows faster than the muscles and tendons around it. The tight Achilles tendon pulls on the back of the heel, irritating the growth plate. It’s most common in girls between ages 8 and 10 and in boys between 10 and 12, particularly those who play sports involving running or jumping. Pain is often worse at the beginning of a new sports season. By age 15, the growth plate has closed in most children and this condition resolves on its own.
How Heel Pain Is Treated
Since plantar fasciitis accounts for the majority of heel pain cases, most treatment research centers on it. The good news: most people recover within several months using conservative measures. The approaches with the strongest evidence behind them fall into a few categories.
Stretching is one of the most effective tools. Stretches targeting the plantar fascia itself (pulling the toes back toward the shin while seated) and stretches for the calf muscles both reduce pain in the short and long term. Clinical practice guidelines give this the highest recommendation level. Foot taping, using either rigid athletic tape or elastic kinesiology tape, provides short-term relief when combined with stretching. Night splints that hold the foot in a flexed position are particularly useful if your worst pain is with those first morning steps. A one- to three-month program of nightly use is the standard recommendation.
Strengthening exercises for the foot and ankle muscles are also recommended. These go beyond simple stretching to include resistance work, like towel curls or calf raises, that builds the supportive muscles around the arch and heel. Manual therapy, where a physical therapist works on joint and soft tissue restrictions in the foot, ankle, and lower leg, is another approach supported by strong evidence.
Shoe inserts and orthotics are a common purchase, but the evidence is more nuanced than marketing suggests. Orthotics alone are not recommended as a standalone treatment for short-term pain relief. They work best when combined with stretching and strengthening. Whether you choose a prefabricated drugstore insert or a custom-fitted orthotic matters less than pairing it with active treatment.
Icing the painful area, reducing or modifying activities that aggravate the pain, and maintaining a healthy body weight all support recovery. Carrying extra weight places more load on the plantar fascia with every step, so weight management is part of the long-term picture for people with recurring heel pain.
How to Tell Your Pain Pattern Apart
A quick summary of what each pattern feels like in practice:
- Plantar fasciitis: Worst with first steps after rest, improves with movement, returns after prolonged standing. Stretching temporarily reduces pain.
- Stress fracture: Worsens with activity, improves with rest. Swelling present. Squeezing the sides of the heel reproduces pain.
- Heel pad syndrome: Deep bruise-like pain in the center of the heel, worse on hard surfaces and barefoot.
- Achilles tendinopathy: Aching at the back of the heel, worsens with activity, tendon may feel thickened.
- Nerve compression: Burning, tingling, or numbness on the inner ankle or bottom of the foot.
Signs That Need Prompt Attention
Most heel pain responds to home treatment over a few weeks. But certain symptoms point to something more serious. Severe pain and swelling immediately after an injury, inability to bend the foot or rise onto your toes, and heel pain accompanied by fever or numbness all warrant prompt medical evaluation. Heel pain that persists at rest, including pain that wakes you at night, or that hasn’t improved after a few weeks of icing, stretching, and activity modification is also worth getting checked.
