Oh no, not again!

I got to Morro Bay last night with every intention of going to Spin class. When I got out of my truck, my left knee buckled and the pain of my osteoarthritis had returned. Understand, I had experienced no pain whatsoever for months, ever since I started taking my anti-inflammatory. I was, in fact, thinking about asking the doctor if I really needed to keep taking it or not. I had even considered starting to do some light running again, against doc's wishes. So much for that! I went ahead and rested it last night, had some light pain today but is much better. I don't have time for a workout tonight, hopefully tomorrow I can do something.
