I pulled my hamstring and i can't rest it. what is the next best thing?

See a doctor: If possible, you should seek an examination by a doctor who can give you pain medication till the muscle heals. If that is a problem, you could use pain medication and try to rest the injured muscle for a few days. It usually takes 1 to 2 weeks for a sprained muscle to get better, . But you need to be sure that it is not torn in which case you have to see your family doctor who may ask for orthoped.
