                                                          Within 48 hours of injury one should use some combination of the following: cold therapy(rest, ice, compress, elevate), a compression bandage to minimize intra muscular bleeding, mobilization of the injured lowered limb in a pain free manner (stretching, strengthening) and consultation of a sports injury specialist.  In the future prevent hamstring injury by performing a proper warm up.
