Nerve damage in the lumbar spine (lower back) can be caused by trauma, an underlying medical condition, or compression of the nerve. The lumbar spine is made up of five vertebrae, labeled L1-L5. Damage to the fifth lumbar vertebrae (L5) can cause pain, numbness, and weakness in the lower body.
The symptoms of L5 nerve damage can vary depending on the cause and severity of the injury. Common symptoms of L5 nerve damage include:
• Pain in the lower back, buttocks, and legs
• Numbness and tingling in the toes and feet
• Weakness in the legs and feet
• Loss of balance and coordination
• Difficulty standing and walking
• Inability to move the foot or ankle
• Loss of reflexes in the foot or ankle
• Difficulty controlling the bladder and bowels
• Pain and numbness in the thighs and hips
If you experience any of these symptoms, it is important to seek medical attention right away. Your doctor will be able to diagnose the cause of your symptoms and recommend treatment options. Treatment for L5 nerve damage may include physical therapy, medications, nerve blocks, or surgery. With timely and appropriate treatment, many people can find relief from their symptoms and regain full function of their legs and feet.
