I am currently taking oxycontin 2x/day and percocet for breakthrough. It doesn't completely take care of the pain - but, it makes it livable for now. I am going to have the nucleoplasty, as you know, w/ the hope that I will be able to wean off the meds and not need them anymore. This is a hope ~ and I realize it w/b sometime before I can go off meds completely.
My point is there is alot of room for you to take medication since you are at such a low level now and taking a immediate release med, percocet. I think I would consider trying the longer-acting meds that are out there (oxycontin, methadone, ms contin to name a few) before I'd go to fusion. That's just my personal opinion. And it may not be what you want to do. But, perhaps you could be on a low dose of long-acting medication w/ a BT and maintain a 3 or 4 pain level for a time. You won't really know that unless you try, I guess. Everyone is different. I started on 10mg oxycontin2x/day in March, and now am @ 20mg. This keeps me around a 4 for a good part of the day, if taken w/ the BT of perc 5mg 2-3x/day. I hate having to take meds....that is why I want to try the Nucleoplasty. But, if That doesn't work....I suppose I would continue w/ meds before I'd ever consider fusion. I would have to be not walking before I'd agree to fusion. Again, my personal opinion.
Good luck w/ your search for the right answer for you.
