The most common reason your heel hurts when you walk is plantar fasciitis, a condition where the thick band of tissue running along the bottom of your foot becomes irritated or inflamed. It accounts for the vast majority of heel pain cases. But several other conditions can cause similar symptoms, and where exactly you feel the pain, when it’s worst, and how it started all point toward different causes.
Plantar Fasciitis: The Most Likely Cause
The plantar fascia is a band of tissue that connects your heel bone to the base of your toes. It supports your arch and absorbs shock every time your foot hits the ground. When this tissue is repeatedly stretched and stressed, small tears develop that lead to irritation and inflammation.
The hallmark symptom is a stabbing pain in the bottom of your foot, near the heel. It’s usually worst with the first few steps after waking up. That morning pain happens because the fascia tightens while you sleep, and those initial steps forcefully stretch it again. The same pattern shows up after long periods of sitting or standing. Pain often eases as you move around, then returns after extended activity.
Plantar fasciitis is more common in people who spend long hours on their feet, carry extra weight, or have recently increased their activity level. Flat feet, high arches, and tight calf muscles all increase your risk. Nearly 90% of people improve with conservative measures like stretching, supportive footwear, and rest, though recovery can take weeks to months.
Achilles Tendinitis: Pain at the Back of the Heel
If your pain is at the back of the heel rather than the bottom, Achilles tendinitis is a strong possibility. The Achilles tendon connects your calf muscles to your heel bone, and it can become irritated in two distinct ways.
Insertional Achilles tendinitis affects the lower part of the heel, right where the tendon attaches to the bone. This type can strike anyone, even people who aren’t particularly active. Noninsertional tendinitis affects the middle portion of the tendon, where fibers break down, swell, and thicken. This type is more common in active people. Both cause pain that worsens with walking, climbing stairs, or pushing off the foot.
Stress Fractures in the Heel Bone
A calcaneal stress fracture is a hairline crack in the heel bone that develops from repetitive impact rather than a single injury. The pain tends to build gradually over days to weeks, which is why many people initially mistake it for plantar fasciitis or general soreness. One distinguishing feature: squeezing both sides of the heel reproduces the pain. With plantar fasciitis, pressing into the bottom of the heel is what hurts.
Stress fractures are more likely if you’ve recently ramped up your walking, running, or training intensity. They’re also more common in people with low bone density. If your heel pain steadily worsens despite rest and doesn’t follow the classic “worst in the morning, better with movement” pattern, a stress fracture is worth investigating.
Heel Fat Pad Syndrome
Beneath your heel bone sits a cushion of fatty tissue that absorbs impact with every step. Over time, this pad can thin out and lose its elasticity. Normal heel pad thickness is 1 to 2 centimeters. When it shrinks below that, you’re essentially walking with less shock absorption, and the heel bone takes more direct force against the ground.
This condition is more common as you age, but it can also result from years of high-impact activity or wearing hard, flat shoes. The pain feels like a deep bruise directly under the heel and tends to worsen on hard surfaces. Unlike plantar fasciitis, it doesn’t follow a strong morning pain pattern. It’s more consistent throughout the day, especially with prolonged walking.
Nerve Compression: Tarsal Tunnel Syndrome
Less commonly, heel pain comes from a compressed nerve. Tarsal tunnel syndrome occurs when the nerve that runs along the inside of the ankle gets squeezed as it passes through a narrow space near the ankle bone. The resulting pain can radiate into the heel and the bottom of the foot, often accompanied by tingling, burning, or numbness.
What sets nerve-related heel pain apart is its character. Instead of a sharp, localized ache, you may notice shooting sensations, pins and needles, or a feeling that part of your foot has “gone to sleep.” In more advanced cases, you might have difficulty curling your toes or notice reduced sensation on the sole. Diagnosing tarsal tunnel syndrome typically requires nerve conduction testing. Nerve-related heel pain is usually one-sided. If both heels hurt, that pattern raises different questions.
When Both Heels Hurt
Bilateral heel pain, meaning both heels are affected, sometimes signals something beyond a local tissue problem. While it’s entirely possible to develop plantar fasciitis in both feet, pain in both heels can also be associated with inflammatory conditions like certain types of inflammatory arthritis. These systemic causes tend to come with other symptoms: stiffness lasting more than 30 minutes in the morning, lower back pain, or pain that’s worse at night rather than with activity. If your heel pain doesn’t fit the typical mechanical pattern, it’s worth a closer look.
Heel Pain in Children
If your child is complaining of heel pain, the likely culprit is Sever’s disease, an inflammation of the growth plate in the heel. It’s the most common cause of heel pain in growing kids, typically affecting girls between ages 8 and 10 and boys between 10 and 12. The pain is usually at the back of the heel and gets worse with running or jumping. Squeezing the sides of the heel reproduces the discomfort. Sever’s disease resolves on its own once the growth plate matures, but rest and cushioned shoes can help manage symptoms in the meantime.
What Helps Heel Pain
For the most common causes, the early approach is the same: reduce the load on the heel and give the tissue time to recover. That starts with footwear. Shoes with a supportive heel and a moderate heel-to-toe drop reduce tension on the plantar fascia compared to flat shoes or going barefoot. Worn-out shoes with compressed midsoles offer little cushioning and can make things worse.
Stretching the calf muscles and the plantar fascia itself is one of the most effective conservative treatments. A simple wall stretch for the calves, held for 30 seconds a few times per day, targets the chain of tissue that pulls on your heel. Rolling a frozen water bottle under the arch combines stretching with icing. Avoiding walking barefoot on hard floors, especially first thing in the morning, helps prevent re-aggravating the tissue when it’s at its tightest.
Over-the-counter arch supports or heel cups can take pressure off the painful area while you’re on your feet. For people whose pain doesn’t respond after several weeks, custom orthotics, physical therapy, or other interventions may be the next step.
How Long Recovery Takes
Most heel pain from plantar fasciitis and similar soft tissue conditions improves significantly within a few months of consistent conservative care. The frustrating reality is that this isn’t a quick fix. Tissue that’s been irritated for weeks or months needs time to heal, and pushing through the pain often extends the timeline. People who stick with daily stretching, appropriate footwear, and activity modification tend to recover faster than those who address it sporadically. The small percentage who don’t improve with these measures may benefit from more targeted treatments, but the vast majority never need them.
