Mild hamstrings do not fully hinder movement, because they are not that painful; however, severe strains are excruciating, making it impossible to stand and walk. Hamstring strains can be in the form of a complete tear, partial tear or a pull. The severity of the injury dictates therequired treatment.
The hamstring is composed of three muscles that run along the back of the thigh, between the hip and immediately below the knee, according to MedicineNet. A hamstring strainoccurs whenone of the muscles is stretched beyond its limit. Hamstring strains typically occur during sudden and explosive movements such as running, jumping or any other physical activity that requires the continuous movement of the legs, as stated by the American Academy of Orthopaedic Surgeons. They cause a sharp pain at the back of the thigh, bringing thephysical activity to an immediate halt.Hamstring injuries are common among sportsmen and athletes such as basketball players, as reported byWebMD.
Ahamstring strain may take months, weeks, or days to heal, depending on its severity. A mild grade 1 strain typically heals readily, while a more severe grade 3 strain may take up to a month to heal because it is a complete tear, as noted by the American Academy of Orthopaedic Surgeons. Most people who suffer a hamstring strain eventually recover full function, after completing treatment and subsequent rehabilitation.
