Hey Carrie,
I'm really sorry that you are still having that bad day. The good thing is that with Lyme and friends things change so much, that you have a pretty good chance of having a better day tomorrow!!!
Now that you have explained why you want to go through with the MRI - I agree. I thought you might be doing it kind of on your own, just to see if those lesion were still there. Now that I understand, I think you should go ahead and get one done too. Only you have to promise to let us know what the results are!! (LOL - you don't really have to promise, but I hope you let us know still!)
