Hi cognizance!
That's a great question and one that's a bit hard to answer...but I can give you my experience and what I've read on the forum about
it.
First, if you're on Tramadol after 'several years' you're doing very well. That's not much of an increase to increase the dosage and not change to a different medicine. When I was diagnosed my doc had been giving me percocet and it wasn't doing much to control the pain. But when the rheumatologist confirmed his diagnosis he put me on oxycontin with percocet for breakthrough pain. I think I tried Tramadol once but that was given to me by the rheumy, I think. Felt like I was taking M&M's...lol But that's just how my body works. I have a friend who could get a full dose effect of percocet by just licking the inside of the container lid. It's all related to our opioid receptors and how they are dealing with the drugs.
If you are wanting to know what comes next after Tramadol, here's a listing of medications and their relative strength. This is only a relative listing as medications work differently for all of us.
www.vaughns-1-pagers.com/medicine/painkiller-comparison.htm The best thing you can do is consult your doctor. Don't be afraid to tell them that your current medication isn't working. It's the only way he's going to know. You don't need to suffer out of worry that you will be chastised or looked down on for asking. If you have a good doctor it's not a problem.
Hope this helps,
Chutz
