Most heel spurs respond well to conservative treatment, and surgery is rarely needed. About 90% of people improve without an operation, though the timeline can stretch to several months. The bony growth itself isn’t always the source of pain. It’s the inflamed tissue around it, particularly the plantar fascia, that typically hurts. That distinction matters because effective treatment focuses on reducing inflammation and mechanical stress rather than eliminating the spur.
What a Heel Spur Actually Is
A heel spur is a pointed calcium deposit on the underside of the heel bone. It forms gradually in response to repeated stress. The leading explanation is that chronic pulling where the plantar fascia attaches to the heel bone causes inflammation and, over time, new bone growth. A competing theory suggests that repetitive vertical compression creates tiny stress fractures in the tendon, and the body lays down extra bone as a protective response. Either way, the spur is a symptom of ongoing mechanical strain, not the primary disease.
Interestingly, many people have heel spurs on X-ray with zero pain. Spurs located within the plantar fascia itself tend to cause more severe symptoms than those sitting above it. And the most common location for a calcaneal spur is actually deep below the plantar fascia, in the muscle origins, which helps explain why the spur’s presence on an X-ray alone doesn’t confirm it’s your pain source.
Stretching and Physical Therapy
Stretching is the foundation of heel spur treatment. Two stretches matter most: calf stretches (standing on a step and letting your heels drop below the edge) and plantar fascia stretches (pulling your toes back toward your shin while seated). Both target the tight tissue that pulls on the heel bone. Doing these consistently, ideally several times a day, gradually reduces tension at the attachment point where the spur formed.
Beyond stretching, strengthening exercises help long-term. Toe curls with a towel, picking up marbles with your toes, and resistance band exercises for the foot and ankle all improve the muscular support around your arch. Physical therapy can also include manual techniques and gait analysis to identify movement patterns that contribute to heel overload.
Footwear and Orthotics
What you put on your feet has a direct effect on how much force hits the spur. A study testing different heel heights found that raising the heel by 2 to 3 centimeters shifted load away from the heel toward the midfoot and big toe. That modest lift reduced compression at the heel by roughly 2 to 4 percent relative to the pain threshold, which was enough to produce a 70 to 100 percent decrease in pain for the majority of participants. For men, a 2-centimeter heel height worked best; for women, 3 centimeters was optimal.
Orthotic insoles work on the same principle. Look for insoles with a deep heel cup (which stabilizes the heel and prevents it from spreading under load), firm arch support (which redistributes pressure along the foot), and cushioning material that absorbs shock. You don’t necessarily need custom orthotics. Quality over-the-counter insoles with these three features can make a meaningful difference, especially in shoes that are otherwise flat or worn out.
Avoid walking barefoot on hard surfaces. Even at home, a supportive sandal or slipper with arch support protects the heel from direct impact.
Anti-Inflammatory Medication
Over-the-counter pain relievers like ibuprofen or naproxen can reduce both pain and the underlying inflammation. NYU Langone Health recommends a 10 to 14 day course for acute flare-ups. These medications work best as a short-term bridge while you build up the benefits of stretching, orthotics, and activity modification. They won’t fix the structural problem, but they can break the cycle of inflammation long enough for other treatments to take hold.
Icing the heel for 15 to 20 minutes after activity is another simple way to manage inflammation without medication.
Shockwave Therapy
If conservative measures haven’t worked after several months, extracorporeal shockwave therapy (ESWT) is a non-invasive option worth considering. The treatment delivers focused sound waves to the painful area, stimulating blood flow and tissue repair. It typically involves three sessions spaced one to two weeks apart.
The Royal Orthopaedic Hospital reports a 75 to 80 percent success rate for heel pain patients treated with shockwave therapy. Side effects are generally minor: temporary pain during and after the session, skin redness, bruising, or swelling. Tendon rupture has been reported but is very rare and mostly associated with patients who recently received steroid injections in the same area.
Steroid Injections
Corticosteroid injections deliver a powerful anti-inflammatory directly to the painful spot. They can provide significant short-term relief, with one study showing favorable outcomes in about 41% of patients who received them. That’s better than the roughly 31% success rate seen with conservative treatment alone in the same study, though neither number is overwhelming.
The tradeoff is risk. Repeated injections can cause the fat pad under your heel to atrophy, permanently thinning the natural cushion that protects the bone. Once that cushion is gone, the heel becomes even more vulnerable to pain. Other potential complications include plantar fascia rupture and nerve injury. For these reasons, doctors typically limit both the number and frequency of injections and advise reducing high-impact activity for about two weeks afterward.
When Surgery Becomes an Option
Surgery is considered only when pain persists after 12 months of consistent non-surgical treatment. Two procedures exist: plantar fascia release (detaching part of the fascia from the heel bone to relieve tension) and direct removal of the spur itself. Sometimes both are done together.
Recovery from plantar fascia release takes about six weeks. Heel spur removal requires closer to three months. After either procedure, you’ll wear a bandage for one to two weeks and possibly a cast, walking boot, or ankle splint for up to three weeks. How soon you return to work depends on your job. A desk job might mean two weeks off; a job that keeps you on your feet could require four weeks or more.
Reducing Heel Stress Long-Term
Heel spurs form because of chronic overload, so prevention comes down to reducing the forces that caused the problem in the first place. Body weight plays a significant role. Obesity is one of the factors most strongly correlated with spur formation, because every extra pound multiplies the impact on your heel with each step. Even modest weight loss reduces that load substantially.
Replacing worn-out shoes before the cushioning breaks down, maintaining calf and foot flexibility through daily stretching, and using supportive insoles during prolonged standing or walking all help prevent recurrence. If you run or do high-impact exercise, gradually increasing intensity rather than making sudden jumps gives your tissues time to adapt without triggering the inflammatory cycle that leads to new bone growth.
