Hi, Kelly. It sounds like you're doing all the right things -- keeping in touch with your doctors (if you haven't already, you need to call with any new symptoms that come up), getting that MRI, which will be able to give them some ideas of what is going on with you.
For now, there's not much you can do except keep track of any new stuff that comes along, and if any of the symptoms subside, you probably want to note that, too.
Your symptoms could be MS...but could be a lot of other things, too. MS is one of those disorders that..everything else has to be ruled out, before doctors will settle on that as a diagnosis, and that's what the MRI is about -- to rule in or rule out other things.
do keep in touch, and come back with any questions, and then when you get your MRI results. Take care.
...I am not a doctor, nor health professional, and don't pretend to be one, here.....
