I see the rheumy again in august. You know, i'm going to be assertive and ask him about the cold sores and other symptoms. I really don't want to change rheumys because he's really the best doctor i've seen so far for my symptoms. And i've seen five (yes, 5) neurologists. And he beats all of them! I didn't mention before but he found a disease (a parasite actually) that I had, that no one had tested me for before this. So, I took the treatment for that, and right now we're waiting to see if this has helped. I think he's got his work cut out for him where i'm concerned. Because i'm a regular at the lab (always giving blood for tests) I have short conversations with the lab techs about my ordeal. They speak very highly of this doctor and assure me, that if anyone will find out what's wrong with me, it will be him. They say, "he won't give up." i'll also ask him about the acyclovir. I've heard of that.
