I was sitting at the hairdressers and all of a sudden I went all dizzy and then a big slow rush & boom to my head. I haven’t had this for years but this one was the longest & worst I have ever had. It wasn’t very nice & I really felt like I was going to faint.
Does anyone know what this was & what may have triggered it, I had breakfast and walked the dogs, nothing unusual that morning.
Any suggestions please .
