I agree don't assume anything..... ever when dealing with MS.
I was in a very similar situation as you and jumped out of an MRI machine. I made excuses for each symptom I had last year. Finally I "woke up" and said this is not normal I need to know what is happening to me. It took me a long time to be ready and comfortable with the fact I would most likely will be diagnosed with MS.
I loved having my head buried in the sand pretending I was perfectly fine. I did that for 5 years after my CIS at age 19. But once my second attack (last year) was finishing up I ran out of excuses and explanations lol..... It has been nothing but smooth sailing since then. I have made all the proper changes that need to be done with diet, exercise, nutrition, medication, and life style modifications to fight back.
Ask yourself this, will you be happier with "your head in the sand"?..... ignorance is bliss.
Will you be happier knowing whatever it is and getting your answer?
It could be many different things as well, it doesn't have to be MS. It could be as simple as a b12 deficiency or other nutrients.
Betsyjoy, I applaud you for dealing with this crap 30 times longer than I have
lol. Only god knows what I will be like 30 years from now..... especially if they cant "cure" this crap or at least stop it.
