It's not a headache at all, and it's hard to explain the feeling. It's like my brain's trying to pop out of my skull sometimes! Sometimes it feels like its floating. I was diagnosed with Temporal Lobe Epilepsy about 2 years ago and was put on Lamictal. That medicine made my head feel exactly like this, but I haven't taken it in over a year (since March 2006) and this just started happening a couple of weeks ago.
I stopped taking the medicine because of how it made me feel. Now, I feel like that anyway! It's doing it right now, and sometimes I grit my teeth when it happens.
Does anyone else experience this?
