8 years ago I suffered a brain injury. The only lasting effects have been random memory blanks; wherein for 5-15 min I experience teporary amnesia, not knowing who or where I am or what I'm doing; and occasional migraines. I also have family history of epilepsy. I'm wondering if any of this could be related to a new symptom I developed recently.
I've begun experiencing a strange periodic pressure in my skull. It feels as though my brain is squeezed with the pressure 'rolling' through my skull. It always starts on the crown of my head, shifts down to cover the back of my head before rolling forward stopping behind my eyes before dissapating entirely. It isn't painful just uncomfortable. At most it lasts about 45 seconds in total though it is often only 15-20 seconds in duration. It causes mild balance loss during and for about 5-10 seconds after. I usually pause what I am doing during an episode so I'm not certain if it impares judgement or cognition. I can talk during an episode.
