Very interesting book you have mate. I too need an acl recon and even though I have had this sciatica for many years I cannot rid myself from the dull pain aswell as the pins and needles down the leg.
It deffinately feels muscle related as I sit down to repair mobile phones but I tend to sit on a leg as I sit and swap now and again. I also tend to watch tv leaning at an angle too. This I think is not helping me at all and I need to address these issues. I'm only 29 and I don't want to plagued with this forever. I just wish you was from the uk as I live far away from the ones in the uk.
Many thanks for your help and I hope I can progress.
