Herniated disc, severe back pain, no nerv siatica,took antinfla. and muscle relax.pills. after 4 week , no pain but my big toe is numb,what to do?

Numb big toe: Sound like your L5/S1 disc is involved if you are getting numbness in your big toe. A neuropathic med like gabapentin, lyrica, (pregabalin) etc. may help with numbness. Your L5 nerve root is affected. Might benefit from a selective nerve root block of your L5 nerve root with some steroid like dexamethasone, celestone, etc. Physical therapy may help your back symptoms too.
