About a year and a half ago I started to have pain in my right knee. I went to a doctor and had an MRI done that showed what appeared to be arthritis and tendinitis. They gave me a RX for an anti-inflammatory and had me do some P.T. which never worked. So I still have pain in my knee and it only get's worse when I go to work which is most likely what brought on all the pain in the first place. So I have to ask what do you do or use for knee pain, and if I am having pain when I work can I see a workman's comp doctor even thou its been longer than 30 days from start of pain?
