Generally speaking, for lumbar muscle strain, it is recommended to rest for three to four weeks. During this time, it is important to avoid strenuous activities and exhaustion to allow the symptoms of lumbar muscle strain to gradually alleviate. However, this type of lumbar muscle strain is due to chronic damage to the lumbar muscles. It is difficult to achieve complete healing through rest alone, and the healing time can be very long. It is possible that after resting for three to four weeks, the symptoms can be completely relieved, but symptoms such as back pain may recur after subsequent excessive exertion or intense exercise. Therefore, for patients with lumbar muscle strain, in addition to absolute rest, we also recommend using some physical therapy methods, such as massage and acupuncture, to help relieve back pain and promote the recovery of lumbar muscle injuries.
