Has anyone suffered hamstring strain - at the lower end behind the knee. What kind of rehab would you suggest for the hamstring. I'm stretching it out - which does help but I also think my back may be pulling on the hamstring it's really tight, so I also need some good stretches for my lower back. I've also started doing single lying leg curls to strengthen the hammy and also lower back work too. In all I need help so if you can help I'd be grateful.
