What causes lumbar plexus pain?
The most frequent causes are high-energy trauma, sports injuries, penetrating trauma, and surgery that results in damage to the plexus. In particular, injuries that cause damage between the spinal cord and spinal ganglion (proximal) lead to severe pain.
What does a lumbar plexus MRI show?

Can lumbar radiculopathy cause hip pain?
Lumbosacral radiculopathy is a disorder that causes pain in the lower back and hip which radiates down the back of the thigh into the leg. This damage is caused by compression of the nerve roots which exit the spine, levels L1- S4.
What nerves are affected by L4 and L5?
