Did they write you Tramadol on your last visit.If they wrote it and you've decided to stop taking it,after seeing them,I'd wait til next appointment.
If you discussed your concerns about
the Tramadol and "serotonin syndrome" and they didn't prescribe it your last visit then I think it would be ok to let them know that you're in pain.
Of course waiting til your next appointment would probably be the best.
I'm not sure of all the facts so I hate to guess on something as important as your Pain Contract.
