this is soo annoying im 19 and i have been getting cold flashes every day about 10 times a day. It sort of feels like cold water randomly starts running through my body throughout parts of the day. These also occur alot when i am getting dressed and when i am exercising. I have also been having heart palpitations and diarhea , I have been to a endocrinologist i have gotten blood work for thyroid and cbc everything came back fine. Someone please help me figure out what is wrong with me 
and by the way this is at ALL times of the day so this cannot be caused from my period.
