Thanks everyone for the good thoughts and prayers.
The results of the MRI came back with good news! There are no lesions in my neck or spinal cord and the rest doesn't look too different than the fist MRI. A couple of more lesions, but no one's in a tizzy, so I guess it's ok.
I am going to do a round of steroids, though. The good news is that I don't have to go in for 3 days of steroids through an IV. Instead I'll be taking them for 10 days. I'm not sure how steroids help get over a relapse, but at this point I don't really care, either. Even though I definitely have trigeminal neuralgia, the doc thinks the flair up is because of the MS, so he wants to do the steroids first instead of putting me on the anti-seizure meds full time for the TN. At least, I think that's what's going on.
All I know for sure is that for the next 10 days I'm taking a huge amount of steroids. The nurse said the side effects could be an upset stomach, bloating and water gain, inability to sleep, and moodieness. Some would say, "And that would be different for you how?" And they'd be right ;-)
The best news though is that since I don't have to do the IV treatments and there's nothing else horribly wrong, I can go on the day trip to Minneapolis. Al and I are going with a riders' club to the motorcycle show up there. Al asked how many yarn stores he was going to have to go to to make this up to me. But I told him none, since I'm going to dump him and spend time with a blogging buddy. It should be a lot of fun. And 6 hours on a bus gives me lots of knitting time.
