Low back pain caused by over-exertion may be caused by trauma, lumbar disc herniation, ureteral stones and other factors. 1. Trauma: Excessive force may lead to lumbar muscle strain, or even fracture may cause symptoms of lumbar pain. It is recommended to consult a doctor in time for a clear diagnosis. Muscle strain should pay attention to rest and relax the waist muscles, which can gradually relieve the symptoms, and fracture usually requires conservative treatment or surgical treatment. 2. Lumbar disc herniation: If you exert too much force on your lower back, you may suffer from lumbar disc herniation. The protruding nucleus pulposus may cause irritation to the surrounding nerve roots, thus causing the symptoms of lumbar pain, which may be accompanied by radiating pain and numbness in the lower limbs. 3. Ureteral stones: Excessive force in the lower back may cause stones originally present in the renal pelvis to fall into the ureter. As the ureter is narrow, when there are stones in it, spasmodic contraction may occur, resulting in the symptoms of low back pain. When the back pain occurs after exerting oneself too much, it is recommended that the patient consult a doctor in a timely manner to clarify the cause of the disease and actively carry out targeted treatment.
