It is arthritis : It is arthritis! we have over 150 different types of arthritis. It depends on which one of these it is. It is now your physician's responsibility to find out what type of arthritis it is.

You are describing a joint effusion, which is a build-up of fluid in a joint. Many things can cause an effusion, such as inflammation, trauma, bleeding, and infections. If your knee does not improve, seek follow-up wwith your physician.

Inflammation: You are too young to have significant osteoarthritis (wear and tear arthritis) but something caused the joint lining to produce fluid. Possibilities are injury, torn cartilage, viral arthritis, or some type of inflammatory immune arthritis (there are many). Bacterial infections are usually pretty obvious from the fluid and the clinical picture. Find out the fluid test result and ask "what's next.".
