Hi...so I got my latest MRI results but I need some help interpretting them

since the nurse was less than knowledgable. First MRI was August of 2012 w

an w/o contrast and showed nothing. Last MRI was 1/21/13 and showed a

couple areas of white matter which the nurse kept saying was common in

people with migraines. I never have migraines. I also have a capillary

telangiectasia. She said for that it was usually harmless. I asked her what

the doctor wanted to do and she said he just wants to check my brain again

months from now. I really couldn't get anything else out of her. Prior to

getting the MRI done the doctor had said he would want to do an LP. There

was no mention of that when they called me for the results. I am very

worried as I have been for 1.5 years since my symptoms started. I'm just

looking for someone to help me understand this and why they don't seem to

be worried about them. Should I get a second opinion? My life is going

downhill so fast. I have progressively worsening symptoms in my legs and

feet involving tingling, burning, and numbness. More recently weakness in my

ankles. I also have shooting pains in my elbow and feet sometimes. I had

burning tongue for like 2 weeks that has gone away now thankfully. I also

have spells of vertigo that last a few days and bouts of blurry vision that

lasts weeks at a time. Thanks for reading and any advice you are willing to offer!
