Pain After Disc Removal

Back in the beginning of october had had surgery to remove two herniated discs. The pain had been reduced by 50% at the time. Prior to surgery my back never hurt, the pain was in my hip and in my a stomach, as a matter of fact it took three doctors six months and the physical therapist actually was the one to discover it was actually my back causing all these problems. I first did two months of physical therapy, than the epidural steriod injection (which actually made my pain more severe) and the doctor finally said surgery was the only hope.
I can do whatever I want without pain, unless I sit or stand in one position for any length of time. As soon as I sit even for a minute the pain (pressure) starts and the pain continues until I take pain relievers and lay down. I had another mri done and another epidural steriod injection, the mri showed three smaller herinations and lots of scar tissue. The steriod injection made me worst again and now my pain is just slightly less than prior to the surgery. My current doctor now wants to do a spinal fusion, this was not done with the first surgery. I have opted to go for a second opinion, but just am so fustrated, and cannot stand the pain anymore. I am almost at the year mark from the time this all started. Has anyone else experienced these same syptoms, any suggestions? I am so tired of being on pain medication just to make it through the day. I am still working as a buyer, and my employer is so understanding, and cannnot afford to be out of work anymore. If anyone has experienced any advice? How did you manage? What medications did you take? Does the pain ever go away?
I apologize for the long post but I am at my witts end and cannot take it anymore.
