Sarah, welcome to this community and welcome to “The Gap”. Most of us have been where you are now for at least three months. (That would be the average time for the first treatment to start working, if you are lucky enough to have the first bullet hit the target.) The Gap is not a good place to get stuck.
Have a look through our Complementary Therapies section, there’s a lot of really good stuff there. But please remember that the best pain control comes from having your disease in remission. If your rheum doesn’t seem to be able to pull that one off, you need to find someone else who will try. There are various rheumatologists around the country who are specialists in this wretched disease, and please be prepared to invest in a move like that if your current rheumie isn’t finding the treatment sweet spot that allows you to have your life back.
Good luck with the Remicade, and hope you find some comfort between now and remission.
