Men’s back pain may be related to cold, lumbar muscle strain and lumbar spine disease, etc. The specific situation also needs to go to the hospital for examination and diagnosis. 1. Cold: especially teenagers and young people, do not pay attention to the waist to keep warm after exercise sweat, cold stimulation caused by lumbar muscle and ligament spasm, thus causing the symptoms of lumbar pain. 2. Lumbar muscle strain: the disease is common in men who bend over for a long time and men who sit for a long time. This kind of pain is more obvious in the morning, mainly because of long time standing or sitting, which leads to lumbar muscle strain, ligament stretching ability to reduce, thus leading to the symptoms of lumbar pain. 3. Lumbar spine diseases: for example, lumbar disc herniation, lumbar spine slippage and so on. When lumbar disc herniation compresses the nerves, the symptoms of lumbar pain will appear, accompanied by discomfort in the buttocks and lower limbs. When a lumbar spine slips, its weight-bearing function decreases and the stress on the muscles, ligaments and soft tissues around the lumbar spine increases. Over time, this produces discomfort such as pain and soreness. Men whose back pain cannot be relieved for a long time after rest should go to the orthopedic department of the hospital to clarify the cause of the disease and adjust the treatment in time.
