Over several months i have had recurring pain in/around my right knee. I can honestly say it isn't always painful, but when it is i cannot weight bear and sometimes feel as though i will lose my balance. I can only walk approx three steps without having to grab onto something or someone. I use to get relief when i kept my leg straight - now it doesn't help. Bending my knee while seated is occasionally painful. Recently i had an xray- the Doctor's office called me to come back into their office to review the results of the xray. The Doctor said there is a 'black spot' in the knee xray and the physician referred to the 'black spot' as a 'red herring' - he also said he wanted me to get a bone scan done and he didn't want to wait for the scan to be done. Then he said everything's probably ok - i'm worried. I have the bone scan next week. Does anyone have anything they can tell me about this because i have been trying to research this and so far haven't found anything that would give me any answers. I actually thought the pain might go away when spring arrived - it hasn't - there's no change. I am actually afraid to go out on my own now because i don't know how far i will be able to walk or if my knee will give out and my balance will be off. I'm hoping someone can give me a few answers. I'm worried. Thanks.
