Hi Matt, and welcome.

You have every right to be anxious if you dont feel good and no none can figure it out. There are more than 100 diseases that can mimic MS, so getting a diagnosis can be tricky. Make sure they do a bucket of blood tests to rule out the easy stuff. Vid def, lyme, lupus, and so forth. As they start to rule out what you dont have, they may be able to uncover what you do have.

Hang in there.
