Now that I have a copy of the MRI report, although it doesn't say one lesion that is what my PCP said. The report says "Minimal nonspecific periventricular T2 white matter hyperintensities". In any case, I found online a "McDonald's" MS dx that seemed to require more than one lesion in order to confirm MS dx.

Is there anything else that is common that could cause lesions?

I did have a ANA blood test to ruled out Lupus, Lyme disease, etc.

Are white matter hyperintensities ever tumors? And wouldn't something show up in my blood test if it was a tumor?

My MRI of cervical spine showed:
- Mild degenerative spondylosis of the cervical spine extending from C4-5 thru C6-7
and
- Mild spinal canal stenosis at C5-6 and C6-7

there isn't any mention of lesions. Couldn't all that cause my arm tingling and electrical shocks?

Guess I really need to see the neuro, just have so many questions.
Thanks everyone for your advise. Helps to hear from people that have been in the same situation before.
