Symptoms of Synovitis
Synovium can be described as a fimy, thin material that forms a sac enclosing a movable joint within your body. Inside of a healthy joint, this synovium is usually barely one cell thick and it works with cartilage to reduce friction.

There are two kinds of cells located inside the synovium. One produces fluid that helps to lubricate the joint, while the other keeps the joint clean through consuming materials that are deemed to be unwanted. If the synovium is inflamed, it produced excess fluid that causes the joint to swell and cause discomfort.

Major symptoms of synovitis includes swelling, with fluid, as well as pain, stiffness, and a feeling of a "pop" every time you move the joint.
