The hazards of lumbar muscle strain include: 1. Acute lumbar sprain. The acute lumbar sprain, in the acute phase of treatment is not very thorough, the injured muscle, fascia, ligament repair is not good, will produce a large scar adhesion, so that the waist function is reduced, easy to lead to the occurrence of new lumbar injury. 2, lumbar muscle fascia aseptic inflammation. Long-term bending or long-term sitting work people, lumbar back muscles in a long-term pull state, over time there will be spasm, ischemia, edema, adhesions and so on, some people call it aseptic inflammation. 3, the accumulative injury. The ligaments of the lumbar muscles are vigorously injured, which can cause small-scale fiber rupture, bleeding, and exudation, and these tissues are stretched and compress the intrinsic nerve fibers and produce lumbago. 4. Patients with lumbar muscle strain who have repeated episodes can cause more serious lumbar disc herniation or lumbar spinal stenosis because of the muscle imbalance in the lumbar back caused by lumbar muscle strain, and the corresponding lumbar vertebrae bones will be affected, which is This is one of the more serious complications of lumbar strain.
