I've had this pain for about 2 months now. It's in the lower half of my back towards the right of my body. When this occurs I also have a pain in my knee on the same side. It seems to flair up when I'm walking (doesn't have to be far) The pain tends to feel like a pull or a rip which then makes my leg feel as though it's numb. It got that bad when I was on holiday I just sat and cried. Has anyone else had this same type of pain and could you shed a light into what it might be??
