Hi there i went to a fitness class last tuesday night and i nearly fainted, i had felt a little off the past week before i went to this fitness class but that certian day i felt fine. When i got to the fitness class i was good untill i got a stich across my stomach, then i had to stop as i nearly passed out. ever since i nearly passed out i have had a really bad headache also bad head pains like some one is stabbing me, last night i also notice i had sort of numbing in my right hand now it feels like it has krept up to my shoulders it just doesnt feel normal, my head is still aching it aches before i go to bed and as soon as i wake up. i have been 2 a few different doctors one i had blood tests nothing showed up the other told me it was a migrane and not to worry, i feel very off balance and not myself i am really worried :( just wondering if you could help me please?
