About a 2 months ago I had arthoscopic surgery on my left knee. They found inflammed tissue and tissue that was suppose to go away as I got older and it never did so they took that out as well as smoothing out cartilidge. I went through therapy for about 3 weeks and then they said I didn't have to come anymore but just recently my knee gave out walking down stairs and just walking in a straight line and ever since then I have been real shakey and my heart has been pumping real fast also. Whenever I stretch my hamstring on that knee too I get a lot of pain in the knee and it feels like i could blackout. Do I need to go back to my knee doctor and get it checked out again?
