Stretching to the waist generally return to normal in a few days, depending on the degree of muscle tissue damage and treatment, can not be generalized. After stretching the waist, there will be different degrees of muscle or ligament damage. If the muscle damage is mild and the patient’s activities are not significantly restricted, timely treatment, such as acupuncture, moxibustion, Chinese herbal fumigation, etc., will generally require 1-2 weeks to recover after treatment. If the local ligament damage is serious, the patient’s lumbar spine activity is obviously restricted, extensive subcutaneous bruising occurs, and serious cases are even unable to walk. After conservative treatment, it usually takes 3-4 weeks to recover, and the exact time varies from person to person. If the symptoms do not improve or worsen, it is recommended to take X-rays and MRI films regularly to clarify the degree of recovery. During the treatment period, patients need to pay attention to strict bed rest, local hot compresses with towels, and also can follow the doctor’s instructions to take oral blood-activating and nerve-nourishing drugs.
