question: hi. I was rear ended but on the right, by a land rover 6 weeks ago, I m having physiotherapy as i had a lot of pain in the middle of my back also low down and going down my buttocks and leg to my heel, all on the left side. The pain in my left buttock is driving me mad but the physiotherapist said its a tight hamstring not nerve damage. I have been stretching my hamstring but doesn t seem to be helping. or maybe I just need to be patient. please help. Marie
