Lumbar Radiculopathy at L4: Symptoms and Signs
When the L4 nerve root is affected, patients often report lower back pain that radiates down the inner thigh and into the shin. Muscle weakness in the quadriceps and trouble performing knee extension are typical symptoms. Some individuals also experience numbness or a tingling sensation in the lower leg.
Therapy for L4 radiculopathy aims to reduce lumbar spine inflammation and decompress the nerve. Chiropractic adjustments, targeted stretching, and strengthening exercises can be beneficial. Addressing lumbar disc herniation or spinal stenosis—common culprits of nerve compression—is key to resolving pain and improving function.
