You serm to be having typical symptoms of radiculopathy
caused by nerve root
cmpression which in your case is quite evident on MRI
The sequence for treatment in disc protrusion
is firstly conservative with the help of medicines and back exercises. If this does not relief pain then doctor might go for local epidural steroid
injection in your back.
The last treatment resort , if all this fails is surgery, which frankly in your case is not required as there seems to be only a disc protrusion.
As for now in your case I would suggest a local epidural steroid injection by an expert.
Medication would include nucoxia-MR , Pregablin, complamina , short term steroid course.
Just be cautious that there should be no sensation loss as this would mean that permanent nerve degeneration is taking place.
I hope my suggestion is of help.
