Heel pain can make walking, standing, or exercise uncomfortable, but the source is not always the bottom of the foot. The plantar fascia, Achilles tendon, nearby bursae, nerves, and heel bone can all be involved. Where the pain occurs and when it worsens may offer useful clues, though symptoms can overlap. Understanding common heel pain causes can help you decide what to change, what to monitor, and when to get a professional evaluation.
Plantar Fasciitis
The plantar fascia is a strong band of tissue that runs along the bottom of the foot and connects the heel to the toes. Plantar fasciitis develops when this tissue becomes irritated, often where it attaches to the heel bone. People commonly feel a sharp or aching pain under the heel, especially with their first steps in the morning or after sitting for a while.
Pain may ease as the foot warms up, then return after prolonged standing, walking, or activity. A sudden increase in exercise, limited ankle flexibility, or shoes with poor support can contribute. These clues do not confirm the cause by themselves. If symptoms persist or keep returning, a podiatrist can assess your foot and recommend care suited to your activity and health.
Achilles Tendinopathy
The Achilles tendon connects the calf muscles to the back of the heel. Achilles tendinopathy causes pain, stiffness, or tenderness along the tendon or near its attachment to the heel. Symptoms often feel worse during activity or when getting moving after rest. The area may also feel thickened or tender to touch.
A rapid increase in running, jumping, or hill training can overload the tendon, particularly when recovery is limited. Pain at the back of the heel can also involve nearby structures, so avoid assuming it is simply tendon soreness. Reduce activities that sharply worsen symptoms and arrange an evaluation if pain continues, limits walking, or becomes more intense.
Other Possible Causes
Pain beneath the heel can also come from a bruised heel pad, a stress injury in the heel bone, or irritation of small nerves. A stress injury may cause pain that builds with weight-bearing activity and improves with rest. Burning, tingling, or numbness can suggest nerve involvement. These patterns are not definitive, but they are useful details to share during an assessment.
Pain at the back of the heel may involve bursitis, which is irritation of a small fluid-filled sac near the Achilles tendon. In children and teenagers, a growing heel bone can become irritated during active growth. Some inflammatory conditions can affect both heels or cause symptoms elsewhere. A clinician can consider your age, activity, medical history, and examination findings when identifying the cause.
When to Seek Care
Seek prompt medical care if heel pain follows a significant injury, you cannot bear weight, or you notice marked swelling, redness, warmth, or a wound. Sudden severe pain or a popping sensation near the Achilles tendon also needs urgent assessment. If you have diabetes or reduced sensation in your feet, contact a healthcare professional early about new pain or skin changes.
For less urgent pain, note where it occurs, when it started, what activities worsen it, and whether it is worse after rest or during exercise. Wear comfortable shoes and temporarily scale back activities that aggravate symptoms, but do not push through worsening pain. A podiatric evaluation can help distinguish among causes and guide a safe plan.
Heel pain has several possible sources, and similar symptoms can require different approaches. Track the location and timing of your pain, adjust activities that aggravate it, and seek an evaluation if it persists or interferes with daily movement.
