Most people with a heel spur don’t know they have one. Heel spurs rarely cause pain on their own, and the only definitive way to confirm one is through an X-ray. If you’re experiencing heel pain and wondering whether a spur is behind it, the reality is that the spur itself probably isn’t the problem. The pain is almost always coming from the soft tissue around it, most commonly the plantar fascia.
What a Heel Spur Actually Is
A heel spur is a bony calcium deposit that builds up on the underside of your heel bone, right where the thick band of tissue on the bottom of your foot (the plantar fascia) attaches. This buildup happens gradually over months or even years. Repeated strain on the foot muscles and ligaments, along with small tears in the membrane covering the heel bone, triggers your body to deposit extra calcium at the attachment point. Over time, that calcium hardens into a small, pointed growth.
About 11% of the adult U.S. population has a heel spur visible on X-ray, and many of those people have no symptoms at all. In one study comparing people with plantar fasciitis to people without it, 89% of the plantar fasciitis group had a spur on imaging, but so did 32% of the comparison group who had no heel pain whatsoever. The spur is often a sign that stress has been building in the area, not necessarily the direct source of your discomfort.
What the Pain Feels Like
When people talk about “heel spur pain,” they’re usually describing the symptoms of plantar fasciitis, the inflamed tissue that often accompanies a spur. The hallmark is a throbbing pain on the inner side of the bottom of your heel, worst with the first steps you take after getting out of bed or standing up from sitting. Those initial steps can feel like a sharp, stabbing sensation right at the base of your heel.
The pain typically eases after a few minutes of walking as the tissue loosens up, but it tends to return if you stay on your feet for a long stretch. You might notice it flaring after exercise rather than during it, or after spending hours standing on a hard floor. This “worse after rest, better with movement, worse again with overuse” cycle is the most recognizable pattern.
Can You Feel a Heel Spur?
You can’t feel the spur itself by touching your heel. These calcium deposits sit on the underside of the bone, buried beneath layers of fat and tissue. What you can do is press firmly on the inner edge of your heel pad, right where the arch starts. If that spot produces a sharp, localized pain, it suggests irritation at the plantar fascia attachment point, which is exactly where spurs form. Pulling your toes back toward your shin while pressing on the area often intensifies the pain.
This self-check can help you identify the likely location of the problem, but it won’t tell you whether a bony spur has actually formed. An X-ray is the only way to know that for certain.
Conditions That Feel Similar
Several other heel problems produce pain that overlaps with what people attribute to heel spurs. Knowing the differences can help you describe your symptoms more accurately.
- Heel pad syndrome causes a deep, bruise-like ache in the center of your heel rather than the inner edge. It’s especially noticeable when walking barefoot or on hard surfaces. The pain sits right in the middle of your heel pad, not along the arch.
- Calcaneal stress fracture starts as pain only during activity but can progress to hurting even at rest. A key difference: squeezing both sides of your heel bone with your hands produces pain, whereas plantar fasciitis pain comes from pressing on the bottom.
- Tarsal tunnel syndrome involves a compressed nerve near the ankle and produces burning, tingling, or numbness that can radiate into your heel, sole, and toes. The pain tends to worsen with standing and walking but improves when you elevate your foot or wear looser shoes.
- Nerve growths (neuromas) near the heel can mimic plantar fasciitis, but the sensation leans more toward burning or tingling rather than a sharp stab. Pressing on the area may reveal a small, tender lump.
How Heel Spurs Are Diagnosed
Your doctor will start with a physical exam, pressing along the bottom of your foot and asking about your activity level, how the pain started, and when it’s worst. They’ll check for tenderness at the inner heel, look at your foot structure, and may move your foot and toes into different positions to see which motions reproduce the pain.
The definitive step is an X-ray. Heel spurs show up clearly on a standard lateral (side-view) foot X-ray as a small, pointed projection extending forward from the heel bone. Many people first learn about their spur when an X-ray is taken for general heel pain investigation. In roughly half of all plantar fasciitis cases, a spur is visible on imaging, but its presence doesn’t change the treatment approach. The spur is treated as a secondary finding. The focus stays on reducing inflammation and mechanical stress in the surrounding tissue.
Who Is Most Likely to Develop One
Heel spurs develop from chronic, repetitive stress on the heel. The people most at risk share a few common profiles. Those between ages 40 and 60 are in the peak window, and carrying extra body weight significantly increases the load on the plantar fascia with every step. People whose jobs keep them standing for long hours on hard floors, including healthcare workers, factory workers, and teachers, are particularly vulnerable.
Biomechanics play a major role too. Having flat feet or unusually high arches changes how force distributes across the bottom of your foot, concentrating more strain at the heel. Tight calf muscles pull on the Achilles tendon, which connects to the same bone, adding tension to the area where spurs form. Runners, dancers, and anyone who recently ramped up high-impact activity are also at elevated risk.
Worn-out shoes or footwear with poor arch support accelerate the process. If the midsole of your athletic shoes is compressed and no longer springy, they’ve lost the cushioning that protects your heel from repetitive impact.
What to Expect if You Have One
If an X-ray confirms a heel spur, the treatment targets the inflammation and tissue damage around it rather than the spur itself. Most people improve with a combination of rest from aggravating activities, stretching the calf and plantar fascia, supportive footwear, and over-the-counter insoles or heel cups that cushion the impact zone. Ice applied to the heel for 15 to 20 minutes after activity helps control inflammation in the short term.
The spur doesn’t go away on its own, but it doesn’t need to. Once the surrounding tissue calms down, the spur typically causes no trouble. Surgery to remove a heel spur is rare and reserved for cases where months of conservative treatment haven’t provided relief.
Heel pain that persists during walking, gets worse with activity over several weeks, or comes with visible swelling, redness, or difficulty bearing weight deserves professional evaluation. People with diabetes or circulatory conditions should be especially attentive to any heel problem, since foot issues in those populations can escalate quickly.
