Thanks for the info about the antibody test. My chills only last about 1/2 hour, and my temp does go up a degree during that time. It does somewhat seem like an allergic reaction.

I've had two different sets of allergy testing pre-ms dx. On both times, as the tech put the shots on my back, I would blow up like I was going to be allergic severely to everything. Then she would come back after 15 minutes and I'd have no reaction whatsoever. Thus I was never put on any med for anything.

It is just interesting that the Ty is doing about the same with me. I have a reaction right after getting the med, but then nothing.

I'll call my neuro's office today and leave a message about possibly getting the antibody test. I know his nurse is out on vacation, and she is always so good about getting back to me quickly. So I probably won't have anything definitive for awhile.

But I really appreciate the feedback!
