Understanding Achilles Tendinitis: Types, Treatments, and When to Seek Help

Pain along the back of the heel can feel frustrating — especially when it lingers and begins to interfere with both daily activities and exercise routines. One common cause of this discomfort is Achilles tendinitis. This condition develops when the tendon connecting the calf muscles to the heel bone becomes irritated or inflamed, often as a result of overuse or repetitive stress.

Recognizing the type of Achilles tendinitis you may have and understanding your treatment options can make a big difference in recovery and long-term tendon health.

Types of Achilles Tendinitis

There are two main types of Achilles tendinitis:

● Non-insertional Achilles tendinitis: This occurs in the middle section of the tendon. It is more common in younger, active individuals and is usually linked to repetitive activity such as running, jumping, or sudden increases in exercise intensity.

● Insertional Achilles tendinitis: This affects the lower portion of the tendon where it attaches to the heel bone. Unlike the non-insertional type, insertional Achilles tendinitis can occur in both active and less active people.

Both forms of the condition can develop due to factors such as repetitive stress, poor footwear, abrupt changes in physical activity, or underlying biomechanical issues.

Treatment Options for Achilles Tendinitis

For many patients, rest and conservative treatments (such as activity modification, stretching, and physical therapy) are the first steps. But when these are not enough, more advanced options may be considered.

Shockwave Therapy

Shockwave therapy is a non-invasive treatment option particularly useful for chronic Achilles tendinitis. High-energy sound waves are directed into the injured tendon to stimulate blood flow, encourage tissue repair, and reduce pain. Treatment ofteninvolves multiple sessions and is considered when standard therapies do not provide adequate relief. While not suitable for everyone, many patients report improved mobility and decreased discomfort after completing a course of shockwave therapy.

Platelet-Rich Plasma (PRP) Therapy

PRP therapy uses the patient’s own blood to promote natural healing in the tendon. A blood sample is drawn, processed to concentrate the platelets, and injected into the injured portion of the Achilles tendon. These platelets release growth factors that promote tissue repair and help reduce inflammation. PRP is often recommended if conservative approaches don’t work and is minimally invasive compared with surgery.

Current research is ongoing, but many patients with chronic Achilles tendinitis have experienced encouraging results.

Surgical Treatment

For severe or persistent cases that fail to respond to conservative measures, surgery may be necessary. Depending on the damage, procedures may involve:

● Removing damaged tissue

● Repairing tendon tears

● Lengthening the tendon to relieve tension

Recovery after surgery usually involves a period of immobilization followed by a structured rehabilitation program, including physical therapy. While surgery can be effective, it does carry risks such as infection, nerve injury, or extended recovery, which is why it is typically considered a last resort.

When to Seek Care

Ongoing heel or Achilles pain should not be ignored. The earlier Achilles tendinitis is properly diagnosed and treated, the better the outcome. By addressing the condition before it becomes chronic, patients often avoid more invasive procedures and experience quicker recovery.
