to risk being an echo i third that...i dislocated my left knee dec 6 2007 at 7 pm and here on june 12 th i have a host of problems with my other knee mostly due to favoring and over use, but i HAD to work and so i ended up taking near poisonous doses of nsaids to keep going. now my other leg is paying. but the liver is fine, doc gently told me leave that 8x reg dose alone...but moral is don't risk being healthy 6 months later for a week or two of training and then see it all slip away from you...
