I haven't been running much since I've been having problems with my knee. The orthopedic specialist has me wearing a light brace on it whenever I am not in bed. He doesn't think I have a torn meniscus, maybe arthritis or something floating around. I'm on celebrex, but I dont think its working. My knee is as painful today as it was when I first made the doctor appointment. I have a follow up in late October to see where its at, hopefully, not in as much pain. In the mean time, he said I could run, so I ran a 5K yesterday. My time wasn't great. I went to about the turn around and my knee started acting up. I finished, but very slowly.
