I ve had knee problems for years, I have worked construction most of my life , I m 65 yrs old and still work everyday, mostly light repair work. Maybe 10 yrs ago I was sitting on my bed with my left leg curled under my right leg. My wife and I sat there for maybe 2 hrs talking ( sitting in the same position ) . When I stood up my knee locked up , hurt like hell. It would swell up, I d pack it in ice , sometimes for hrs before I would feel some relief. The pain s been getting worse ever since , but it will go away for a day or two, then it s right back to where it was. I wear a brace I got from Walgreens for a few days at time and it will improve for a day or two....or three if I m lucky. The pain seems to come mostly from the inside of the knee joint , almost like something is sticking out from under the knee cap or from inbetween the knee joint itself. Just wondering if this is from a torn meniscus or something else and what is the correct approach to hopefully fix this problem. Thank you in advance for your help, Randy YYYY@YYYY
