Understanding Bone Spurs: What They Are and How They Form
A bone spur, also called an osteophyte, is an extra piece of bone that grows on top of normal bone. These growths are usually smooth and can range in size from very small to quite large. Bone spurs most commonly develop on bones in the spine, heel, foot, hip, knee, and shoulder, though they can form on almost any bone in the body.

Bone spurs develop over time as the body responds to stress, injury, or age-related changes. When joints experience repetitive stress or wear and tear, the body sometimes tries to repair the damage by building extra bone tissue. This is why bone spurs are more common in people over 60, though younger people can develop them too. According to research, bone spurs develop in about 35% of people by age 60.
Several factors contribute to bone spur formation. Osteoarthritis is one of the most common causes. As cartilage breaks down in joints, the underlying bone changes shape, and spurs may form. Repetitive motions in certain jobs or sports can also trigger bone spur growth. For example, people who spend years doing activities that stress the same joint—like runners, construction workers, or musicians—have higher rates of bone spurs. Previous injuries to bones and joints, even injuries that healed long ago, can lead to bone spur development years later.
Inflammation in joints and tendons also promotes bone spur growth. When tissues around a joint become inflamed repeatedly, the body sometimes responds by creating extra bone. This is why conditions like plantar fasciitis, which causes heel pain from inflammation, often leads to heel spurs. Poor posture, muscle weakness, and obesity can increase pressure on joints and make bone spurs more likely to form.
Practical takeaway: Understanding what causes bone spurs helps you recognize early warning signs. If you have pain in joints or notice reduced movement, talking with a doctor early may help prevent or slow bone spur development.
Recognizing Symptoms and When to See a Doctor
Many people have bone spurs without knowing it. In fact, studies show that about 10% of people with bone spurs have no symptoms at all. These spurs cause problems only when they press on nearby nerves, tendons, or other tissues. When symptoms do develop, they vary based on where the spur is located.

Heel spurs, the most common type, often cause sharp pain in the heel, especially when walking or standing. The pain is usually worst in the morning or after resting. People often describe it as a stabbing feeling. Spurs in the spine can cause neck or lower back pain, numbness, tingling, or weakness in the arms or legs. In the shoulder, bone spurs may limit how far you can move your arm and cause pain with certain movements. Spurs in the foot can make walking difficult and may cause the foot to feel unstable or unbalanced.
Other possible symptoms include stiffness in joints, especially after rest, and reduced range of motion. Some people experience swelling or redness near the affected area. The pain may come and go or stay constant. It might get worse with activity and improve with rest, or it might feel about the same throughout the day.
You should consider seeing a doctor if you have persistent joint or heel pain that lasts more than a few weeks, pain that interferes with daily activities or work, numbness or tingling in your limbs, or pain that does not improve with rest or over-the-counter pain medication. A doctor can examine you, ask about your symptoms, and perform imaging tests like X-rays or ultrasounds to confirm whether bone spurs are causing your pain. Early evaluation is valuable because it helps identify the problem and allows treatment to begin sooner.
Practical takeaway: Keep a simple record of when and where pain occurs and what activities make it worse or better. This information helps doctors understand your condition and choose the right treatment.
Nonsurgical Treatment Options for Bone Spur Management
Most people with bone spurs never need surgery. Many treatment options focus on reducing pain and maintaining function without an operation. These approaches work by reducing inflammation, improving joint movement, and protecting the affected area from further stress.

Rest is often the first step. Reducing activities that trigger pain gives tissues time to heal and inflammation time to decrease. This does not mean complete bed rest—gentle movement and light activity are usually encouraged. Ice therapy, applied for 15 to 20 minutes several times daily, can reduce swelling and numb pain. Many people find relief by alternating ice with heat therapy, which increases blood flow and reduces stiffness.
Over-the-counter medications like ibuprofen or naproxen can lower inflammation and ease pain. These medications work best when taken regularly rather than only when pain is severe. Topical creams containing anti-inflammatory ingredients may also provide relief for spurs close to the skin surface.
Physical therapy is highly effective for many people. A physical therapist teaches stretches and strengthening exercises that improve how joints work and reduce stress on affected areas. Stronger muscles around a joint provide better support and protection. For heel spurs, specific stretches for the calf muscles and plantar fascia can significantly reduce pain. Studies show that people who do physical therapy exercises regularly have better outcomes than those who do not.
Other helpful treatments include wearing supportive shoes or custom orthotics (shoe inserts) that reduce stress on the affected joint, losing weight if overweight to decrease joint pressure, and using assistive devices like canes or walkers when needed. Some people benefit from corticosteroid injections, which reduce inflammation directly in the affected area. These injections provide temporary relief and may be repeated every few months.
Practical takeaway: Start with basic treatments like rest, ice, and stretching. If these do not help after four to six weeks, talk with a doctor about other options like physical therapy or injections.
Advanced Treatment Options and Medical Procedures
When nonsurgical treatments do not provide enough relief, doctors may recommend more advanced options. These treatments address the problem differently and may provide longer-lasting results, though they also involve more risk and recovery time than basic approaches.

Extracorporeal shock wave therapy (ESWT) is one option. This treatment uses sound waves to break up bone spurs or stimulate healing. It is most commonly used for heel spurs and has helped many patients. Studies show that about 50 to 60% of people experience significant pain reduction with ESWT. The procedure takes about 15 to 20 minutes and does not require cutting the skin. Some discomfort during treatment is normal, but it typically resolves quickly.
Ultrasound-guided injections offer another approach. A doctor uses ultrasound imaging to see exactly where to place an injection of medication or platelet-rich plasma (PRP). This precision helps ensure the treatment reaches the right spot. PRP involves injecting a concentrated solution made from the patient's own blood, which may promote healing of damaged tissues.
Radiofrequency ablation is a procedure where a doctor uses heat generated by radio waves to reduce nerve pain caused by bone spurs. This works well for spurs that cause pain by irritating nearby nerves. The effects usually last several months to a year.
Surgery becomes an option when other treatments fail and pain significantly limits daily life. Different surgical approaches exist depending on where the spur is located. Heel spur surgery involves removing the spur and repairing the plantar fascia. Spinal bone spur surgery may involve removing the spur to relieve pressure on nerves. Most surgical procedures are performed through small incisions, which reduces recovery time compared to traditional open surgery. Recovery typically takes four to eight weeks, depending on the procedure and the person's overall health.
Practical takeaway: Before choosing an advanced treatment, discuss with your doctor how long recovery takes, what results you can realistically expect, and what risks are involved. Get a second opinion if you are unsure about surgery.
Home Care and Lifestyle Changes for Long-Term Management
Managing bone spurs successfully often depends on daily choices and habits. Simple lifestyle changes can significantly reduce pain and prevent bone spurs from getting worse over time.

Choosing the right footwear is especially important for heel and foot spurs. Shoes should have good arch support, cushioning in the heel, and a comfortable fit without tight pressure. Avoid high heels and shoes with minimal
