Hi Guys , i'm a 20 year old female and i have been getting these near blackouts lately. When i stand too long or even stand up normally , my legs and arms go numb (i lay or sit down immediately) ,i get this semi migraine , my eyes see black and white spots and my ears ring. I sleep a lot as well , my fiance says i sleep too much sometimes because i will be in bed by 6pm and still be tired. Can anyone relate or give advice on what i can do ?
