From the squats at boot camp, I suspect. Did not have anything before ...
Going to see sport doc at HP on 9/29. It seems a little better today but it may just be overshadowed by my next injury, an over-extended big toe joint, left.
Dr. Abraham diagnosed a pinched meniscus but no tear. Thought it was not too serious and indeed, it's mostly gone. Got some strengthening exercises for the knee. http://cfospruns.blogspot.com/2011/10/injury-woes.html
