The recovery time for a sprained hamstring needs to be judged by the severity of the patient’s condition and cannot be generalized. If the patient has only a mild soft tissue and fascia injury, the soft tissue and fascia injury can be recovered within 1-2 weeks under normal circumstances. However, if the patient’s injury is moderate or moderately severe, the recovery time is at least 4 weeks, during which the patient needs to elevate the affected limb and fix it properly to facilitate venous return and reduce swelling. If the patient has ligament rupture and avulsion after the sprain, it is possible that surgery will be required after the professional evaluation, and the recovery time after surgery will be at least 4 weeks. Regardless of the severity of the sprained hamstring, patients need to pay strict attention to rest and protection to provide the best conditions for injury recovery. At the same time, patients note that they should not exercise too early, otherwise it is easy to cause ligament relaxation, and later it is easy to form a habitual sprain.
