The most common reason your heel hurts is plantar fasciitis, a condition where the thick band of tissue running along the bottom of your foot becomes inflamed. But heel pain has several possible causes, and where exactly you feel the pain, when it’s worst, and what it feels like all point toward different answers. Here’s how to narrow it down.
Plantar Fasciitis: The Most Likely Cause
The plantar fascia is a strong, stretchy band of tissue that connects your heel bone to the ball of your foot, forming the arch on the bottom of your foot. When it’s overused or stretched too far, it swells and becomes painful. That’s plantar fasciitis.
The hallmark symptom is a stabbing pain on the bottom of your heel, especially during your first steps in the morning or after sitting for a long time. The fascia tightens while you rest, and those initial steps force it to stretch again. The pain typically fades as you move around, then returns after long periods on your feet. If this pattern matches yours, plantar fasciitis is the most probable explanation.
People who spend long hours standing, have recently increased their activity level, carry extra weight, or wear flat, unsupportive shoes are most at risk. Tight calf muscles also play a major role because they pull on the heel and increase tension across the fascia.
Pain at the Back of the Heel
If your pain is behind the heel rather than underneath it, the Achilles tendon is the likely culprit. Achilles tendonitis typically starts as a mild ache above the heel after running or physical activity and gradually worsens. The pain can occur in the middle of the tendon or right where the tendon attaches to the heel bone. The attachment point version tends to be more stubborn and is common in people who’ve been active for years.
A closely related condition, retrocalcaneal bursitis, causes pain in nearly the same spot. The difference is subtle: bursitis produces warmth and swelling right next to the tendon, and squeezing the sides of the heel just in front of the Achilles tendon reproduces the pain. With tendonitis, the tenderness is more directly on the tendon itself. Both conditions worsen when you rise up on your toes.
Heel Spurs: Less Important Than You Think
Many people assume a sharp pain in the heel means a bone spur. Heel spurs are real, but they’re often a red herring. Studies of the general population show that 11 to 16 percent of people have heel spurs on X-ray without any pain at all. The spur itself is rarely the source of your discomfort. In most cases, the pain attributed to a “heel spur” is actually plantar fasciitis. The spur is simply evidence that the fascia has been pulling on the bone for a long time.
Nerve Compression in the Heel
If your heel pain comes with burning, tingling, numbness, or a “pins and needles” sensation, you may have tarsal tunnel syndrome. This happens when the tibial nerve gets compressed as it passes through a narrow channel on the inside of your ankle. The pain typically radiates into the bottom of the foot and sometimes the toes, and it can cause weakness in the foot muscles over time.
Nerve-related heel pain feels distinctly different from the aching or stabbing of fascia or tendon problems. The burning and electrical quality is the key clue. It often worsens with prolonged standing or walking and may flare up at night.
Stress Fractures and Fat Pad Thinning
A calcaneal stress fracture (a small crack in the heel bone) causes pain that worsens steadily with weight-bearing activity and improves with rest. Unlike plantar fasciitis, which loosens up as you walk, stress fracture pain gets worse the longer you’re on your feet. You may also notice bruising, warmth when you touch the heel, and stiffness. Stress fractures develop gradually, often in runners or people who’ve suddenly ramped up training. An MRI is usually needed to confirm the diagnosis since standard X-rays can miss early stress fractures.
If you’re older and feel a deep, bruise-like pain directly in the center of your heel when walking or standing, the fat pad on the bottom of your heel may be thinning. This cushion of fatty tissue naturally loses thickness and elasticity with age, leaving the heel bone less protected from impact. The pain is worst on hard surfaces and feels like walking on a pebble. It differs from plantar fasciitis in its location (dead center of the heel rather than slightly forward) and the fact that it doesn’t have the classic “first step” morning pattern.
What You Can Do at Home
For most heel pain, and especially plantar fasciitis, a consistent stretching routine is the foundation of recovery. The American Academy of Orthopaedic Surgeons recommends a program lasting 4 to 6 weeks, performed 3 to 5 days a week at minimum. Key exercises include:
- Calf stretches (straight and bent knee): Hold for 30 seconds, relax for 30 seconds, and repeat. Aim for 2 sets of 10, nearly every day.
- Golf ball roll: Roll a golf ball under the arch of your foot for 2 minutes daily. This helps loosen the fascia directly.
- Towel stretch: Loop a towel around the ball of your foot while seated and gently pull your toes toward you. Hold 30 seconds, rest 30 seconds, 2 sets of 10.
Strengthening matters too. Current clinical guidelines recommend resistance training for the foot and ankle muscles, not just stretching. Simple exercises like towel scrunches with your toes, single-leg calf raises, and short-foot exercises (where you try to shorten your arch without curling your toes) build the support system around the fascia.
Ice the painful area for 15 to 20 minutes after activity. Rolling your foot over a frozen water bottle combines icing with a gentle massage. Over-the-counter anti-inflammatory medication can take the edge off during flare-ups.
Shoes That Help
What you put on your feet matters more than most people realize. Look for shoes with a heel-to-toe drop of 8 to 12 millimeters, which reduces the load on your heel during walking. A firm heel counter (the rigid part that cups the back of your heel) minimizes wobble and takes strain off the fascia. The sole should be cushioned enough to absorb impact without being so soft that your foot sinks in and loses stability.
If off-the-shelf shoes aren’t enough, prefabricated arch supports from a pharmacy or shoe store can help control overpronation (the inward rolling of the foot that strains the fascia). Custom orthotics are an option for persistent cases.
When Heel Pain Needs Professional Attention
Most heel pain resolves with consistent home care over several weeks. But some situations call for a medical evaluation sooner. Severe pain and swelling immediately after an injury, inability to bend your foot downward or rise on your toes, heel pain accompanied by fever, and numbness or tingling in the heel all warrant prompt attention.
For chronic plantar fasciitis that hasn’t responded to stretching, strengthening, and footwear changes after a few months, shockwave therapy is one option. This treatment uses pressure waves to stimulate healing in the damaged tissue, and specialized centers report success rates of 75 to 80 percent in patients with stubborn heel pain.
