The symptoms of low back pain at the age of 17: 1. If the low back pain radiates to the perineum and is accompanied by hematuria, consider that it may be caused by urinary stones. 2. Long-term ambulatory study causes myofasciitis of the low back muscles, and if it is accompanied by radiating pain in the buttocks and lower limbs or numbness, most of them are caused by lumbar disc herniation. 3. If the pain is simply low back pain, consider whether it is due to lumbar muscle strain or sports injury, resulting in damage to the soft tissues of the lower back. Therefore, for 17-year-old lumbar pain, patients need to rest in bed and avoid strenuous activities. If there is no relief within a short period of time, you must go to a regular hospital in time to improve the lumbar MRI or B ultrasound, and choose a reasonable treatment method after the cause is clear.
