this has happened about 3 or 4 times but it's getting worse and i'm starting to worry. this is what happens:

  • ears ringing so loud i can't hear anything
  • vision is largely just black spots and spots of light. can't focus on anything
  • super dizzy to the point of not being able to move, walk, i just sit on the ground and try to regulate my breathing. i almost blank out, as in loosing track of time and sometimes no recollection of actually sitting down.
  • heart pounding very hard and noisily 
  • very faint and nauseous. always expect to pass out or throw up but never have. although i imagine if i stayed standing i would collapse
  • feeling as if overheating or hyperventilating 

i generally recover in what i think is about 15-30 minutes, but feeling nauseous and slight ear ringing continues for about 24 hours. i thought it might have something to do with not breathing enough so i make a concious effort to breath in & out steadily but it doesn't seem to have made a difference. i'm female and have no past serious health concerns or anything to note. young, good diet and usually feel quite healthy and fit although have been rather head achey lately.

should i be worried and should i see a doctor? could this be a sign of more serious health issues?
