The recovery time for a pulled or strained hamstring depends on the severity of the injury. Strengthening the hamstring with light activity while in recovery mode will help the injury heal faster, states WebMD.
Those suffering from a pulled hamstring should avoid going back to their previous physical activity level until the leg can be moved freely, and no pain is caused by any movement. Otherwise, the hamstring may become re-injured and permanently weaker, notes WebMD. While the hamstring is healing, ice packs should be applied. Using a cane or crutches, resting with the leg elevated and taking over-the-counter pain medication may help as well, states the Mayo Clinic.
