Mri shows small herniation on l5s1, mass effect on s1. numbness and pain are l5 dermatoes, eg big toe numbness, is this common?

Mismatch: Be careful about concluding abnormality is cause if pain reconcile with diagnostic injections mismatches are common in failed surgical attempts Look at l5 s1 foramen and other cause of l5 root impingements need to work toward a reconciled confirmed diagnosis

Complex: First you have MRI demonstration of S-1 compression, but you say your symptoms are at L-5, which raises question in my mind of an additional disc fragment affecting this nerve root. The complexities may affect a conservative approach to your problems, and surgery may be needed. Get opinion from spinal surgeon.
