If your doc giving you the Sub is a good pain management doctor too, they should have alternatives to
Ultram. Again,
with your history, I would be very, very careful.
I don't know the nature of your pain, so it's hard to say. But do all you can before you jump back on any pills... that's the only thing I can suggest, if your pain level can tolerate it. Again - this soon, it very well could seem worse as it may be rebound pain... which should soon get much, much better.
