I have osteo arthritis. I have the feeling of swelling inside the knee, especially when i overdo it, and of course that it cuts back the flexibility a lot. It looks normal, but it is painfull. I use asprin or ibuprofen when it gets too much for me. I am shure many have the same condition and complaints. My question is "has any doctor said to anyone exactly what part or parts it is in there that swells".
