I typed an entire answer then the Medhelp gremlin took it away, so I'll start over.
All of your symptoms do occur in MS and an MRI could be the final piece to the puzzle. Just remember, MS is a disease of exclusion. Has your neuro done testing to rule out mimics?
Don't panic if the MRI isn't classic for MS, mine wasn't either. My neuro treated the symptoms as he continued testing for mimics. I had every test known to man. Finally, a consultation with an MS specialist and a year later, I received my diagnosis.
You may not get your diagnosis from the MRI. It's a big let down but if there are mimics left to test for ,then they need to be done so the correct treatment is given. After all of my testing, MS was the only one left standing.
We have a Health Page on this specfic topic. The Health Pages can be found at the top of the page next to the yellow icon. They contain a wealth of information on a variety of subjects. Below is the link to the specific page on mimics.
I know you are anxious for a diagnosis. Everyone is anxious to get anwers to what is wrong. I hope your anwers are in your MRI. Good luck!
