How to treat lumbar nerve pain?
Current treatments available for spinal cord patients with lumbar injuries include: 1 Drugs: Non-steroidal anti-inflammatory (NSAID) drugs are used in treating spinal cord injuries. The quicker these drugs are initiated after injury, the better the result for the patient by reducing inflammation around the spinal cord. 2 Surgery: Surgical decompression of the nerves and fusion of the vertebrae are done to reduce pressure around the spinal nerves, and fixate the spinal column around the spinal cord injury. This can help to restore some function in a person’s lower back anatomy, especially by removing cysts. 3 Therapy: Physical therapy is done to encourage strength in the areas that are affected by spinal cord damage, as well as maintain function in the non-affected area.
