What is the quickest way to heal a moderate hamstring injury?

For a new/recent : Injury start rice (rest, ice, compression with a wrap, & elevation) to rest the affected area. Nsaids, eg, Ibuprofen can help pain & swelling. Gentle massage/stretching exercises within limits of discomfort, then gradually increase frequency and range of motion of the hip and knee joints. Heat after 3-5 days helps. Pain meds (creams), eg bengay (or others) can be helpful. Increase activity slowly.
