It is the unusual increase in synovial fluid that occurs in the joint capsule. This promotes the increase of in-ear pressure and thus causes unbearable pain. It can present as arthritis and usually affects all joints.

Synovitis: what are the symptoms?

It is the medical term for inflammation of the joint. This explains why it already forms a sign of disease, trauma and infection whose causes can be multiple. It results in a relatively painful swelling of the joint which is sometimes followed by redness or joint heat characterizing inflammation. Note that pain is the most common sign of synovitis.

However, in this case, it can still wake you up at night especially during the days following its beginning.

Sometimes, osteoarthritis causes synovitis centered on a joint in crisis during the inflammatory phases. In addition, it also includes metabolic factors such as gout attack or hemochromatosis. Finally, the infection which is usually bacterial, but can also turn out to be viral.
