I Was Just Reading The Posts About Sudden Head Indentions.

I was just reading the posts about sudden head indentions. I found a small intention this morning about the size of a nickel. It definitely has not been there very long. I have had problems in the last year with "seizures". Not the typical kind. Just blanking out for a period of time, still functioning but not remembering anything when I come out of it. I'm on anti seizure medicine. I have had scans, MRI, eeg, mra, etc. Nothing definitive. This sudden intention has scared me. My memory has gotten worse also. Any ideas?
