MRIs, MRAs and Gabapentin

So back in April I started having some sensation issues with the right side of my face along with some muscle twitching. I went to the MD back then and they thought I maybe had shingles without the break out. I got put on Gabapentin (Neurontin) and the symptoms seemed to go away. I was scheduled for an MRI but chose to see if the meds worked first. They did, so fast forward to July and i change jobs and run out of the meds. The symptoms come back and worse. Still no breakout. I finally had the MRI a couple of weeks ago and it turned out basically normal except for some "popcorn calcifications" in the right frontal lobe . There were 2 to be exact. Well, stupid me got on the Internet and typed in MRI and Popcorn calcifications......not a smart thing to do. I freaked myself out because apparently popcorn calcifications are seen in MRIs of people who have either migraines or MS- Multiple Sclerosis.....and I don't have migraines. Yesterday I met with the Neurologist and he walked in a said "You do not have MS." And I didn't even ask him that. I wanted to scream out " PLEASE tell me I don't have MS" when I was walking down the hallway and saw him going into another room, but I refrained. So Yay!!! I do however, they think, have shingles. I am going to have an MRA on the 30th to look at my vascular stuff and a couple of canals. He thinks the original diagnosis was correct and in my case I am just not having the break out, which is great since I do not want blisters on my face. God is great!
