I am going to a pain specialist next week. Is it ok to ask for a pain management agreement?

I was diagnosed with 2 herniated discs three weeks ago by a chiropractor. MRI's to prove it. I have chronic pain from my butt all the way down to my ankle. I feel like I have a sprained ankle anytime I stand. My toes go numb and I have the pins and needles feeling all thoughout my foot. It feels like Mike Tyson punched me in the ***. (Thats how sore it feels). I can stand for 10 mins tops before I have to sit. He was giving me pain meds, such as percocet, vicodin, and even a weeks supply of steroids ( which did nothing). I really liked how the percocet got me through the day. I went back to the chiropractor a few times for refills. Then he started the crap, that he really doesnt want to give me narcotics because of addiction and I am a really young guy (28) blah blah blah. So he gave me a non-narcotic, Ultram (tramadol) which did absolutely nothing for pain. I felt really upset that I had something making me feel normal, to then only get meds that are like taking asprin. The last thing he told me was "Im refering you to a pain specialist, I think thats what you need." After all, their specialty is pain." I think you will feel much better after they give you an epidural" Well, I don't want an epidural. I don't want anyone sticking needles in my back. I would rather wait a couple months to see how I progress before making any decision like this. I have heard many positive and negative things about epidurals. To be completely honest, I just want the pain meds. Would it be wise to ask the pain specialist for the pain management agreement? Are you allowed to do that? I'm just not sure how to go about it without sounding like a junkie. Any suggestions. Please be kind.
