The self-healing time of lumbar muscle strain in young people is related to the severity of the disease and the treatment modality of the patient, and cannot be generalized. Lumbar muscle strain is caused by repeated stimulation of the lumbar muscles, ligaments and fascia to varying degrees due to strain, weight bearing and other adverse factors. If it is a mild lumbar muscle strain, it can be relieved in the short term by paying attention to rest, physical therapy or applying ointments that relax the tendons and activate the ligaments to promote local blood circulation. If the lumbar muscle strain is more serious, so that patients can not live and work normally, you can go to the hospital rehabilitation department or orthopedics, under the guidance of doctors to complete all kinds of exercise to strengthen the lumbar muscles, with physical therapy massage, the symptoms will gradually ease, but still pay attention to prevent recurrence. In addition, because there is no special treatment for lumbar muscle strain, patients with discomfort symptoms should promptly take functional exercise, physical therapy and other ways to relieve, and if necessary, promptly seek medical attention.
