right for me to seek a neuro on my own, if the doctor won't

I had an MRI on Friday- I was unable to have it with contrast, because as they entered it to me, I got sick. I am evidently allergic to the stuff.... anyway, today I got a phone call from my primary doctor's nurse stating, "the MRI was a normal scan- there is a good bit of white matter on your brain, but it can be from a previous injury or your headaches. The doctor said to get another MRI in 6 to 12 months."

I responded with, "No. Please tell the doctor I can not continue this way! I am exhausted by 2 p.m., I have tingling hands and feet, I can't concentrate, can't speak right, the list goes on, and I fall almost daily now."

Would it be right for me to seek a neuro on my own, if the doctor will not? I am hoping she will get back to me with that in mind. For further info, I had my first episode 9 years ago- three weeks of barely walking at all.
