You have gotten some great advice already from peggy.
I too, cannot understand how the MTX isnt working for you because you are still working?? How do they figure that??
Hopefully your GP can put all things raised into perspective for you. I know I always like to see my GP after seeing my Gastro as she is more clued up on things than my Gastro.
Good luck on the 5th Jan and let us know how you went.
