It's so hard when you know you have other things going on than just MS and getting a diagnosis takes time. I am in the same boat right now. I've had tons of tests and no answers yet as to why my blood work is "interesting" and why my joints and tendons swell up so much that what ever joint is swollen is useless.

Have you had an ANA done or any testing for Lupus and other autoimmune diseases other than RA? Those might be helpful to have done. If I remember correctly, don't you also have hemochromatosis? I think that can cause joint issues as well. I got tested for it but the test came back normal.

I hope they find out what else is going on with you soon so that you can be treated. Some DMDs can be used for MS and other autoimmune diseases. My neuro and I had a talk about it and he said some of the RA meds help people with MS too. My goal is to find out what is going on and use one of the crossover meds. If that happens, I'll let you know what they determined is going on and what DMD they decide to put me on to calm this whacked out body down.

Good luck on Friday and let us know how it goes.
