How long it takes to recover from a strained hamstring depends largely on the extent of the injury. Minor symptoms usually take 1 to 3 weeks to recover, while severe conditions may take 2 to 3 months. The tendons of the hand usually include the extensor tendons, flexor tendons, joint capsules and ligaments of the hand. If the strain is mild, with no obvious abnormalities of the above mentioned structures, and only minor symptoms such as oedema, it can usually return to normal in about 1 to 3 weeks after timely measures such as braking, ice application and physical therapy. If the symptoms of a hamstring strain are severe, such as a tear or even a complete rupture of a structure such as a tendon or ligament, in which case surgical reconstruction may be required, the time needed for recovery will be longer, and it may take 2 to 3 months or even longer to recover. In conclusion, the recovery time for a strained hamstring is related to the severity of the condition; the more severe the strain, the longer the recovery time.
