When I was a baby, probably about a year old, I had a CT scan, or an x-ray (can't remember which one) of my head. Then, last year, I had a CT scan done of my head again on 5/31/07. They found a 2 ml lipoma (fatty tissue). They didn't think much of it, so on 6/18/07, I had an MRI done on my head. I know MRI's don't use radiation or anything, but still. Anyway, if you read some of my other questions, you'll see my list of symptoms I've been having.
