Hello Hoshi and welcome to the forum.
I agree that you should consult with a Neuro that specializes in MS. You don't sound like you're making too big of a deal about your symptoms. I'd want to know what's going on, too.
MS is sometimes difficult to diagnose. Plus, you're very young. Your Neuro probably considers your age to be a factor, too. While it's not unheard of for someone your age to have MS it's more common in older people.....usually in their 40's and 50's.
Let us know how you're doing!
