Hi I'm Sam I'm 13 and for as long as I can remember at random points during the day I get extremely dizzy almost to the point of falling, have sharp pain behind my eyes and see black spots in my vison and sometimes my vison goes completely black. This happens from about 1-7 times a day and occasionally it doesn't happen at all some days. I told one of my friends about it after I had to lean on her so I wouldn't fall when it happened one day and I haven't told anyone else. Could someone possibly tell me what dizziness, sharp pain behind my eyes and black spots in my vison is?
