About six months ago I had these convulsions or spasms of my head. they feel kind of like a head rush and there’s a loud noise with it. I get severely dizzy for about ten seconds then it goes away till next time. Sometimes it will only happen once but others it will keep coming and coming. It went away for about a month but is now coming back. I don’t know what to do and it really scares me when I’m driving I’m like paralyzed for a few seconds and it’s very frightening.
