Sprained hamstrings can generally recover by themselves, but if there is a tendon rupture, treatment is needed, the details are as follows: 1. For most patients with sprained hamstrings, the hamstring injury can be gradually recovered through local braking, compression and bandaging with elastic bandages, as well as elevation of the affected limb, continuous cold compresses, and oral anti-swelling and pain medication. 2. It cannot recover by itself and needs to be treated, especially surgical treatment, by surgically re-suturing or rebuilding the ligament tendon and restoring the stability of the ankle joint, so that it can be recovered gradually. Therefore, whether a sprained hamstring can recover on its own depends on the severity of the hamstring injury, if there is no rupture, it can recover on its own, if there is a rupture, it needs to be treated to recover.
