Welcome TJ…waiting to figure out what is going on, especially with MS, is anxiety-producing; many of us waited years for a diagnosis, some got it within weeks of their symptoms presenting.
I don't know how to read MRIs, and it's best left to the pros. Let us know…be an informed health care consumer. Write down dates of onset of symptoms and when they abate; also keep a list of questions for your doc…and if you can bring a family member or friend as a second set of ears it helps.
Knowledge is power...
