Wow, you have an awful lot going on! First, welcome to the board. Second, it sounds like you may need some new Dr's. I can't even imaging not having any pain relief. Perhaps a Pain Management Clinic can help. They do not need to go through your GP to prescribe meds and can manage your meds for you.
If your last pain specialist visit was in 2006, it is WAY past time to go see someone. They will need to reassess your situation and go from there.
I wish you all the best.
