Heel Spur — Causes and Home Treatment

What is a heel spur?

A heel spur (medical name: exostosis calcanei) is a bony outgrowth on the heel bone, a kind of "bony beak." It’s like a stalactite: due to persistent inflammation, minerals are gradually deposited and form an increasing buildup.

It can develop in two locations:

• Plantar (bottom) heel spur: on the underside of the heel bone where the plantar fascia (the ligaments of the sole) attach to the bone
• Posterior (back) heel spur: on the back surface of the heel bone at the attachment point of the Achilles tendon

The bony outgrowth itself is not painful. The pain is caused by the inflamed tissues around it — the tendons and ligaments that the "bony beak" continuously irritates.

The 5 most common causes of heel spurs

1. Overload and repetitive mechanical stress. Heel spurs most often develop when you regularly overload your foot. Runners, people who stand for work, or those who walk a lot on hard surfaces are particularly at risk. Repeated micro-injuries trigger chronic inflammation at the ligament attachment points.
2. Overweight. Every extra kilogram adds load to the heel bone. Excess weight exerts constant pressure on the plantar ligaments, leading over time to inflammation and bony deposits.
3. Inappropriate footwear. Poor shoes — whether too flat, too high-heeled, or simply the wrong size — change the foot’s biomechanics. Shoes that don’t support the arch or lack heel cushioning are especially harmful on hard surfaces.
4. Structural foot abnormalities. Flat feet (pes planus) or very high arches (pes cavus) change how weight is distributed. In both cases the heel bone and plantar ligaments are subjected to increased strain.
5. Tight calf muscles. If your calf muscles are tight, they tilt the heel bone forward and keep the plantar ligaments and Achilles tendon under constant tension. This persistent pulling force favors the development of a heel spur.

6 characteristic symptoms of a heel spur

1. Morning “start-up” pain. The most typical symptom: the first steps in the morning after getting up are extremely painful. This happens because during rest the inflamed tissues "contract," and they react with intense pain on the first load.
2. Sharp, burning pain under the heel. With a plantar heel spur it feels as if there is a nail or pebble under your heel. The pain is localized and pinpointed on the plantar surface of the heel bone.
3. Pain at the Achilles tendon attachment. With a posterior heel spur the complaint appears at the back of the heel where the Achilles tendon meets the bone. It can be especially uncomfortable in shoes.
4. "Warming up" phenomenon. After a few steps the pain may ease — this indicates the tissues are "warming up." Unfortunately, the pain returns after longer standing or walking, and may even worsen.
5. Swelling and warmth. A mild swelling and warmth can be felt over the inflamed area. This signals the body’s inflammatory response.
6. Change in gait. To protect your heel you unconsciously alter your walking pattern. Over time this can overload other parts of the body (knees, hips, lower back).

Diagnosis of a heel spur

The diagnosis is usually straightforward. Based on your symptoms and physical exam, the doctor can suspect a heel spur. An X-ray clearly shows the bony outgrowth — it appears as a characteristic "beak" or "spike."

Important to know: the bony spur develops slowly. If your pain is recent, the X-ray may not yet show the spur. This does not mean there is no problem — simply that the inflammation has not reached the stage where bony deposits are visible.

From a treatment perspective it hardly matters whether a visible bony outgrowth is already detectable. The goal is always to reduce inflammation and pain.

8 effective home treatment methods

Because there is no universal miracle cure, the most effective approach is to combine several methods. The more treatment modes you use in parallel, the better the result. This is the principle of multimodal treatment.

1. Soft laser therapy is one of today’s most effective anti-inflammatory methods for musculoskeletal conditions. The light delivered into the tissues works at the cellular level: it restores the membrane potential of inflamed cells, stimulates ATP production, and accelerates healing processes.
   How to apply? Hold the device directly over the painful area
   Treatment points: plantar surface of the heel, medial edge of the foot, both sides of the heel bone, back of the heel. Perform the treatment daily, for the time indicated by the device at each point.
   Suitable devices: B-Cure Laser, Personal Laser L400 (808 nm wavelength)
   What to expect? In the first sessions the pain may temporarily increase — this is normal and indicates the start of the healing processes. If the pain appeared within the last 1–2 months, soft laser therapy often completely eliminates inflammation and can prevent the formation of a bony heel spur.
2. Therapeutic ultrasound uses sound waves to act on the tissues. Cells are put into a slight vibration, producing a micromassage effect and heat. It increases blood flow, dilates vessels, helps remove waste products and promotes healing.
   How to apply? Apply ultrasound gel to the treatment area Move the applicator head in circular motions over the painful area Treat every other day for 5–10 minutes per session
   Suitable devices: M-Sonic 950, MediSound 3000
3. Magnetic therapy stimulates regeneration of damaged tissues with electromagnetic energy. It is particularly effective for problems of bones, joints and tendons. In heel spur treatment it helps reduce inflammation and accelerate healing.
   How to apply? Place the magnetic coil around or under the heel. A daily 20–30 minute treatment is recommended It can even be used during sleep
   Suitable devices: Magnum 2500, Magnum XL
4. Microcurrent (NEMS) therapy is one of the newest and most effective anti-inflammatory methods, a type of electrotherapy. The weak currents (microampere range) mimic the cell’s own electrical potential, directly affecting cellular healing processes. It strongly reduces pain and stimulates ATP production.
   How to apply? Attach the electrodes to the painful area Use daily The treatment does not cause discomfort
   Suitable devices: Genesy 300 Pro, Premium 400, Runner Pro, Cycling Pro
5. TENS (transcutaneous electrical nerve stimulation) is a drug-free and needle-free pain relief method. Electrical impulses "block" pain signals in the nervous system, providing significant relief. While it does not heal by itself, pain-free periods allow other treatments to be applied more effectively.
   Suitable devices: any device with TENS function (Genesy, Premium, Elite series)
6. Cold and heat therapy. This is the simplest and cheapest method you can start immediately:
   Ice (acute phase): Wrap an ice pack or frozen vegetables in a towel. Hold it on the painful area for 15–20 minutes. Repeat several times a day. 
   Heat (chronic phase): Use a warm foot bath, heating patch or pad. It relaxes tight tissues and improves blood circulation
   Contrast cold–heat: Combining the two creates a pumping effect in the tissues. It enhances metabolism and healing
7. Heel cushioning and insoles. Proper cushioning distributes pressure on the heel and relieves the inflamed tissues. This is one of the most important complementary methods — it increases the effectiveness of every other treatment. Options:
   Silicone heel pad: placed in the shoe to cushion and slightly raise the heel
   Full insole with arch support: evens out load distribution
   Perforated heel pad: relieves the painful point from direct pressure
   Important: choose the right shoe! A stable, well-cushioned, closed-heel shoe significantly reduces symptoms.
8. Stretching exercises and physiotherapy. Regular stretching relaxes tight calf muscles and the plantar ligaments, reducing the pulling force on the heel.
   Basic exercises: Calf stretch against a wall: Stand facing a wall and step one foot back. Keep the back heel on the ground. Lean forward until you feel a stretch in the calf. Hold for 30 seconds, repeat 3 times on each side.
   Tip: the Fit Stretch calf stretching-relaxation device helps you perform the stretch more effectively and comfortably — especially useful if tight calf muscles contribute to your heel spur.
   Plantar fascia stretch: Sit down and pull your toes toward you Feel the stretch in the sole of your foot Hold for 30 seconds.
   Ball massage: Roll a tennis ball or a frozen bottle under your foot. Work especially on the painful area. 5–10 minutes daily. 
   Morning mobilization: While still in bed, before getting up, move your ankle: circles and ankle flexes. This starts blood flow and reduces the first-step pain.

What to expect? Realistic expectations

Treating a heel spur takes time. Everyday walking works against healing — therefore eliminating symptoms requires persistence and often months of treatment.

If you start treatment early (within 1–2 weeks of the pain’s onset): you have a high chance of becoming completely symptom-free and preventing the formation of a bony outgrowth.

If treatment was delayed and a heel spur is already visible on X-ray: you can still eliminate pain and inflammation. You may become symptom-free for years. However, the bony spur remains — neither medications nor physiotherapy can "remove" the extra bone. Only properly performed shockwave therapy in a specialist clinic can "fragment" the bony deposit.

The key is combination: choose at least 3–4 of the methods above and apply them in parallel, regularly. The more directions from which you "attack" the inflammation, the greater your chance of success.

When should you see a doctor?

• If there is no improvement after 2–3 weeks of home treatment
• If the pain is so severe that it prevents you from carrying out daily activities
• If fever, marked swelling or skin discoloration accompany the symptoms
• If the pain started suddenly without an injury

Summary

Heel spur is a stubborn problem, but not incurable. The success of home treatment depends on three things:

• Early start — the sooner you begin treatment, the better
• Combined approach — applying several methods in parallel
• Persistence — healing takes time, don’t give up!

Modern home physiotherapy devices — soft laser, therapeutic ultrasound, magnetic therapy, microcurrent — allow you to perform clinic-quality therapies at home, on your own schedule, as often as needed.
