HI charfit! It sounds like you are experiencing a plethora of symptoms! While I know many of our members have experienced similar symptoms to yours, I don't want to speak for them. I hope they see your post and share their thoughts on this.
I do hope you are able to get that follow up MRI soon. As far as diagnosing MS, physicians generally use a battery of tests to reach a firm diagnosis, which you can read more about here -- https://multiplesclerosis.net/diagnosis/tools-your-doctor-will-use-to-make-a-diagnosis/. An MRI is an important part of the diagnosing process, but is not the only test used.
Unfortunately, many of our members have had a long road to proper diagnosis. That said, I know that a few of our members were diagnosed relatively quickly. It really seems to depend on many factors, including which symptoms are presenting, physician knowledge, accessibility to specialized physicians, etc. I do hope that whatever you are dealing with, you get a proper diagnosis AND treatment very soon!
I also hope you get a reprieve from all those symptoms.
Best of luck and please keep us posted, if you feel comfortable doing so.
Best, Erin, MultipleSclerosis.net Team Member.
