I am a 46 yr old woman having knee trouble for about three months I have been having swelling in my knee off and on with pain but just recently I started working out again at the gym and this last episode was really bad my knee has been hurting non stop for about three days and the swelling won't go down I have been putting hot and cold compresses on it all weekend but nothing is helping I have been taking Aleve for the pain and the swelling and for the last two days my knee has been making this creeking sound like a noisy floor board when you step on it every time I bend it and I can't put very much pressure on it so can you tell me what possibly might be the problem because my family members are trying to diagnose me and they are scaring me
