What a turd your Neuro is..
I hate when they do that..
Tell him if your illness is neurological, then of course it's in your head..... and spine..
The thing is, if you are in the early stages of MS or whatever, it may not yet show up on an MRI. The meds you take for fibromyalgia may help with a neuro prob too.
If I were you, I'd sit tight and see how your symptoms go for awhile. If the numbness, tingling and other neuro sx continue to worsen, then an MRI may tell more.
Try to relax a little and live each day. Do something nice for yourself..
