If men experience symptoms of posterior lumbar distension, it is mainly seen in the presence of local injury, strain, inflammatory reaction and degeneration. Men undertake more social activities in their daily social life, such as many activities and heavy workloads, and often suffer from lumbar injuries and strains. When the local symptoms are not very serious, there will be swelling, soreness and uncomfortable feelings, and there will not be obvious severe pain and dysfunction, but if this disease continues to progress without intervention, lumbar instability and degeneration of the lumbar spine will often occur, resulting in more serious pain and dysfunction. In addition, for older male patients, such as those over 60 years old, the aging of the body often leads to degeneration and hyperplasia of the bones and lumbar spine, producing lumbar instability and soreness and uncomfortable sensations after activity. Patients are advised to protect themselves accordingly, reduce strenuous activities of the lumbar region, carry out observation, and seek medical attention if symptoms are not relieved.
