Tendinitis (also tendonitis), meaning inflammation of a tendon (the suffix “itis” means “inflammation”), is a type of tendinopathy often confused with the more common tendinosis, which has similar symptoms but requires different treatment. The term tendinitis should be reserved for tendon injuries that involve larger-scale acute injuries accompanied by inflammation. Generally tendinitis is referred to by the body part involved, such as Achilles tendinitis (affecting the Achilles tendon), or patellar tendinitis (“jumper’s knee”, affecting the patellar tendon).
SYMPTOMS OF TENDINITIS
Swelling in a region of inflammation or partial tear can be detected visually or by palpation. Symptoms can vary from aches or pains and stiffness to the local area of the tendon, or a burning that surrounds the whole joint around the inflamed tendon. With this condition, the pain is usually worse during and after activity, and the tendon and joint area can become stiffer the following day as swelling impinges on the movement of the tendon.
