I'm still having sciatic pain 60 pain pills later. What do I do?

I have a history of back problems from degenerative disc disease, 2 herniated disc, 1 surgery, 1 broken disc-it has broken twice and landed on the nerve that controls the left leg. So my left leg is killing me and my ock, I live on an armyy base and they do not like giving pain meds. So should I ask for more or try to tough it out? I have tried a million stretches, ice, heat, rest, exercise, this is just driving me crazy.....
