Low back pain may be caused by overwork, lumbar disc herniation, urinary stones, etc. Oral non-steroidal painkillers, nutritive nerve drugs, antispasmodic drugs, etc. can be taken to relieve low back pain. 1. Overwork: If you do heavy physical labor for a long period of time, it will lead to the release of too much lactic acid-like substances from the lumbar muscles, which will lead to low back pain. You can take oral non-steroidal painkillers, such as ibuprofen extended-release capsules and diclofenac sodium enteric-coated tablets to relieve pain. 2. Lumbar disc herniation: Lumbar disc herniation will compress the spinal cord and nerve roots in the spinal canal, thus leading to back pain. In addition to taking anti-inflammatory painkillers, you can also take oral nutritional nerve drugs, such as methylcobalamin tablets, vitamin B1 tablets, etc. to carry out targeted treatment to avoid serious nerve damage. 3. Urinary stones: when there are stones in the body, the stones will make the ureter obstruction and thus lead to back pain. You can take antispasmodic drugs, such as scopolamine tablets, atropine sulfate tablets, etc. to relieve back pain. It is recommended that patients with low back pain go to the hospital in time, after the cause of the disease is clear and active treatment, the specific drugs need to be used under the guidance of the doctor.
