A heel spur is a bony growth that forms on the underside of the heel bone. It is often associated with plantar fasciitis, a condition that causes inflammation and pain to the plantar fascia, which connects the heel to the toes. When walking or standing for extended periods, heel spurs can cause pain to the heel.
Heel spurs develop as a result of repeated stress and strain on the foot ligaments and tendons. Some of the factors that can contribute to heel spurs are:
Overuse of the foot, such as running, jumping, or walking on hard surfaces
Obesity, which puts extra pressure on the heel
Improper footwear, such as shoes that are too tight, too loose, or lack adequate cushioning and arch support
Aging, which reduces the elasticity and flexibility of the foot tissues
Gait abnormalities, such as flat feet, high arches, or pronation (rolling inward of the foot)
Underlying diseases, such as osteoarthritis, reactive arthritis, or ankylosing spondylitis, which can cause inflammation and degeneration of the joints and ligaments
Heel spurs do not always cause symptoms, but when they do, they can include:
Sharp, stabbing, or throbbing pain in the heel, especially in the morning or after periods of rest
Warmth, redness, or swelling in the heel area
Difficulty walking, running, or standing on the affected foot
A visible bump or protrusion on the heel
To diagnose heel spurs, a healthcare provider will ask about the history and severity of the heel pain, examine the foot for tenderness and inflammation, and order imaging tests, such as X-rays, to confirm the presence and size of the heel spur. It may be necessary to perform other tests to rule out other possible causes of heel pain, such as infection, fracture, or gout.
It depends on the severity of the symptoms and the underlying cause of heel spurs whether it needs treatment. A common treatment option is to reduce pain, inflammation, and stress on the heel, and to prevent further damage to the foot tissues.
Medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or local anesthetics, to relieve pain and inflammation
Physical therapy, such as stretching exercises, massage, ultrasound, or shock wave therapy, to improve the flexibility and strength of the foot muscles and ligaments
Orthotic devices, such as shoe inserts, heel pads, or night splints, to provide cushioning and support to the heel and arch, and to correct any gait abnormalities
Rest, ice, elevation, and compression (RICE) therapy, to reduce swelling and promote healing
Lifestyle changes, such as losing weight, wearing proper footwear, avoiding high-impact activities, and modifying the duration and intensity of exercise, to prevent further stress on the heel
Surgery, such as heel spur removal or plantar fascia release, to remove the heel spur or detach the plantar fascia from the heel bone, in cases where conservative treatments fail to provide relief or improve function
Heel spurs can be prevented by taking care of the foot health and avoiding the factors that can trigger or worsen the condition. Some of the preventive measures are:
Wearing comfortable, well-fitting, and supportive shoes that have adequate cushioning and arch support, and changing them regularly
Warming up and cooling down before and after exercise, and stretching the foot muscles and ligaments regularly
Avoiding walking or running on hard or uneven surfaces, and choosing low-impact activities, such as swimming or cycling
Maintaining a healthy weight and a balanced diet, and staying hydrated
Seeking medical attention for any foot pain or injury, and following the prescribed treatment plan
