I have had serious knee pains and problems for about 10 years now (Been on pain killers for 6 years!), and have had 2 operations on my left knee. This is mainly due to football injuries and a very nasty skiing accident. I have recently began a course of therapy on my back, and they have discovered that some of the pain is being caused by trapped nerves in the bottom of my spine, this may require spinal surgery to correct the problem, this is very bad!!!! would only be a little operation, but surgery on my spine, thats a biggy to me!!!!! Because of the physio (Manipulation on my spine) I have been unable to sit at a computer for any period of time or do much of anything (Much to my fiancee's annoyance!), anyways, just thought I'd jot down my thoughts, letting people know why I haven't been doing very much work lately!!!!
