Fibermyalgia recently diagnoised and have been living with chronic multiple conditions for years

Although my spine/pain care management dr, recently told me i have fibermyalgia but my ins. co. wont cover the medication, so he has to call and get a "pre-auth" so they will cover it.  Does anyone use lyrica and does it help?  My spine has 5 buldging discs, three discs with tears in them and some degeneriative disc problems.  I regulary get the streroid shots in my spine but now I am getting thrush in my mouth and throat afterwards.  I am on Norco 10 mg every 4 hours for the pain, i live  with ice packs on all parts of my body.  I feel helpless sometimes to speak up and get more indepth information about my conditions because my present Doctor is very very blunt.  I am trying to work the courage up to discuss my concerns but he is very intimatating.  I am also on soma, requip, LodineBenztropine Mes, Lorazapam, Zoloft, Atenonlol, Nuronton some of those meds are for panic anxiety disorder and now I have been dignoised with Bi-Polar type II,  I dont want to change doctors yet because there are many things i have to go thru in order to get a new doctor and I am on temporary disability since October 2008.  My psychiatrist and therapist told me to apply for long term disability...this feels like an overwelming mess......anyone have any of these conditions?  Using any of these meds or have suggestion about alternative methods because now my pain meds dont work like they used to and I dont want to have the dose increased.......
