A sore heel is one of the most common foot complaints, and in the majority of cases it comes down to plantar fasciitis, a condition where the thick band of tissue running along the bottom of your foot becomes irritated and inflamed. But the location, timing, and character of your pain all matter. Where exactly your heel hurts, when it hurts most, and what makes it better or worse can point to very different causes, some easy to manage at home and others worth getting checked out.
Pain on the Bottom of Your Heel
Plantar fasciitis is the leading cause of pain on the underside of the heel, and it has a distinctive pattern. The pain is worst with your first few steps after getting out of bed in the morning or after sitting for a long stretch. It typically eases after a few minutes of walking, then flares again after prolonged standing or once you stop moving. The most tender spot is usually on the bottom of the foot just in front of the heel bone, where the fascia attaches.
Heel spurs often show up on X-rays alongside plantar fasciitis, but they’re rarely the source of pain. Most people with heel spurs on imaging have no symptoms at all. A spur forms from long-term tension where the fascia connects to the heel bone, but treating the fascia irritation resolves the pain without needing to address the spur itself.
If your pain gets worse the more you move (rather than easing up), and especially if you notice swelling around the heel, a calcaneal stress fracture is a possibility. A useful self-test: squeeze the sides of your heel bone between your thumb and fingers. If that reproduces the pain, a stress fracture is more likely than fasciitis. If stretching temporarily reduces the pain, fasciitis is the more probable cause.
Pain at the Back of Your Heel
When soreness sits behind the heel rather than underneath it, the Achilles tendon area is usually involved. The most common culprit is retrocalcaneal bursitis, where a small fluid-filled sac between the heel bone and the Achilles tendon becomes inflamed. You may notice swelling, warmth, skin color changes around the heel, and pain that increases when you stand on your toes.
This type of heel pain is often triggered by a sudden jump in activity, tight shoes that press against the back of the heel, or skipping warm-up stretches. It can also accompany inflammatory conditions like gout, rheumatoid arthritis, or psoriatic arthritis. If back-of-heel pain develops alongside joint symptoms elsewhere in your body, that pattern is worth mentioning to a doctor.
A Deep, Bruise-Like Ache
Your heel bone sits on a pad of fatty tissue and thick elastic fibers that acts as a built-in shock absorber. Over time, this fat pad can thin out or lose elasticity, leaving the bone less protected. The result is a deep ache right in the center of the heel that feels like stepping on a stone. A firm press to the middle of your heel reproduces it.
This is more common as you age, since the fat pad naturally loses volume and springiness over the years. Carrying extra body weight accelerates the process by increasing pressure on the pad with every step. Unlike plantar fasciitis, fat pad pain doesn’t have a strong morning-stiffness pattern. It tends to build throughout the day, especially on hard surfaces.
What the Timing of Your Pain Tells You
Morning pain that fades within minutes of walking is the hallmark of plantar fasciitis. The fascia tightens overnight, and those first steps re-stretch it. Pain that worsens steadily with activity and improves with rest points more toward a stress fracture or bursitis. Pain that throbs after a full day on your feet, without a strong morning component, may indicate fat pad thinning or general overuse inflammation.
Night pain or pain that persists even when you’re completely off your feet can signal something beyond a mechanical issue. Conditions like nerve entrapment (tarsal tunnel syndrome), bone infection, or systemic inflammatory diseases can all cause heel pain that doesn’t follow typical load-related patterns.
Stretches and Exercises That Help
For most cases of bottom-of-heel pain, a consistent stretching and strengthening routine is the first line of treatment. The AAOS recommends performing these exercises six to seven days per week for four to six weeks.
Heel cord stretch: Stand facing a wall with your unaffected leg forward, knee slightly bent. Place your sore leg straight behind you, heel flat on the floor, toes pointed slightly inward. Press your hips toward the wall and hold for 30 seconds. Relax for 30 seconds and repeat. Do two sets of 10.
Bent-knee heel cord stretch: Same setup, but bend the knee of your back leg. This targets the deeper calf muscle. Hold 30 seconds, relax 30 seconds. Two sets of 10.
Towel stretch: Sit with your legs straight in front of you. Loop a towel around the ball of your affected foot and gently pull it toward you, keeping your knee straight. Hold 30 seconds, relax 30 seconds. Two sets of 10. This one is especially useful first thing in the morning before you take your first steps.
Single-leg calf raises: Stand on your affected foot, holding a chair for balance. Raise your heel as high as you can, then lower slowly. Two sets of 10. If that’s too intense, start with both feet on the ground and progress to single-leg when you’re ready.
Shoes and Support
The shoes you wear every day have a direct impact on heel pain. What works best depends on your arch type. If you have flat or low arches, look for shoes with a straight sole shape and motion control features to stabilize the foot. High arches need extra cushioning to compensate for reduced natural shock absorption. A medium arch does well with a firm midsole and moderate rear-foot stability.
Avoid going barefoot on hard floors while your heel is recovering, especially in the morning. Supportive slippers or shoes with a cushioned sole can make a noticeable difference in those painful first steps. Over-the-counter arch support insoles are a reasonable starting point before investing in custom orthotics.
When Home Care Isn’t Enough
Most heel pain improves within several weeks of consistent stretching, proper footwear, and activity modification. When it doesn’t, there are further options.
Shockwave therapy uses pressure waves directed at the painful area to stimulate healing. The Royal Orthopaedic Hospital reports a 75 to 80 percent success rate for heel pain patients, though most people don’t see significant improvement until 6 to 12 weeks after their final session. It’s typically offered after several months of conservative treatment haven’t worked.
Cortisone injections can provide relief lasting up to several months, but they carry a risk of weakening or rupturing the plantar fascia. For that reason, they’re generally reserved for cases where pain is severe and hasn’t responded to other approaches.
Signs of Something More Serious
Most heel soreness is mechanical, meaning it results from how force is distributed through the foot. But certain patterns suggest a cause that goes beyond overuse. Heel pain accompanied by numbness, tingling, or burning may indicate nerve involvement, such as tarsal tunnel syndrome or peripheral neuropathy. Pain with fever, redness, or warmth that seems disproportionate to any injury could point to infection.
Heel pain that appears alongside stiffness in the lower back, especially in younger adults, is occasionally linked to inflammatory conditions like ankylosing spondylitis. And heel soreness combined with joint swelling in the hands, skin changes, or eye inflammation can be associated with psoriatic or reactive arthritis. These connections aren’t common, but they’re worth being aware of if your heel pain doesn’t fit a straightforward pattern or isn’t improving as expected.
