Voltaren, Neurotin, Muscles relax meds, Psy meds plus Lyrica etc..... so fare none have worked.
At this moment am on 9 diff. meds to help as I've lost sleep ability as pain is so strong so just messing up your whole system if lasting too long. All ways mentioned so far haven't done a thing for me. Chronic sciatic on both side most of time and no space left for shots either so kinda stuck.... Ended up on Opium derivated meds for chronic pain but again limited in its working effect when it reaches 10. I guess each reacts differently to whatever mode or meds so got to use them all till you find the one that will do for you, can be something light, drastic or surgery.... cant tell..... got to find out and do hope you do as chronic pain is the worse way of living.

Bless you
