Lumbar strain is a chronic strain disease that can generally achieve self-healing if patients can persist in improving poor posture. Patients with lumbar muscle strain need to maintain good exercise for the lumbar muscles (such as five-point support, flying swallow exercise, etc.) to increase the lumbar tolerance, improve the muscle strength of the lumbar back muscles and relieve the tension of the lumbar back muscles. The exercise can be done by self-care therapy, i.e. daily standing and sitting posture should be kept correct, after standing or sitting for 30-40 hours, you can get up and move around, avoid keeping the same posture for a long time, and also avoid bending and holding objects and other actions. In addition, for painful areas, patients can also carry out appropriate massage, and at the same time to avoid the waist cold, do a good job of warmth, avoid staying in a wet and cold environment for a long time. For those with severe pain, they can also take targeted treatment, such as acupuncture, physical therapy, oral medication and other comprehensive treatment. Patients with lumbar muscle strain need to pay attention to correcting their posture, changing their lifestyle, paying more attention to rest, avoiding overexertion, and taking in sufficient nutrition to help their condition recover.
