A hamstring strain occurs when the hamstring muscle is either fatigued or stretched beyond its normal range of motion. The hamstring is the group of muscles that run along the back of your thigh. With a hamstring injury, you could also experience a partial or complete muscle tear. You may be more likely to get a hamstring injury if you play soccer, basketball, football, tennis, or a similar sport that involves sprinting with sudden stops and starts. It is very evident when you suffer an acute hamstring pull. It will feel an instant sharp pain like someone kicked you in the back of the leg. Runners often get chronic hamstring pain without an acute strain. This can be attributed to weakness in the hamstring muscle. A Note from the Doctor: Self-care measures such as rest, ice, and a balanced stretching and strengthening regimen may be all most people need. For athletes, it is imperative that they have the myotherapy work done to ensure proper recovery and avoid re-injury. We will utilize stretching and rehabilitative exercises along w/ the myotherapy. The athlete is typically back to full activity in 2-3 weeks. (Same concept and treatment for quad and calf strain as well.)
