Answer:

What Is Enthesopathy?

Enthesopathy is a condition that affects the entheses (e.g., inflammation of the entheses). The entheses are sites of tendinous or ligamentous attachment to the bone. Enthesopathy may be due to an inflammatory condition, such as psoriatic arthritis, or a condition due to injury or overload, such as plantar fasciitis.

Conditions Associated With Enthesitis

Conditions associated with enthesitis include:

Symptoms Associated With Enthesitis

Symptoms include pain and often swelling. In addition to pain and swelling of the heel, other commonly affected areas include the toes and fingers. Toes and fingers can look like a sausage due to swelling at the entheses. With enthesitis, the elbow, pelvis and chest wall may also have pain or swelling.

Treatment of Enthesitis

Treatment of enthesitis is based on the underlying condition. For example, if enthesitis is due to an inflammatory condition, such as psoriatic arthritis, treatment may include:

For plantar fasciitis unrelated to an inflammatory condition, heel inserts and NSAIDs are used.
