Hi, I'm 18 years old and I've been experiencing a few unusual symptoms for about a month (maybe more):
1) I have an absolute intolerance to the heat - I can't stand places such as malls, classrooms, gyms, places where the temperature is hot and/or the air is heavy et cetera.
2) When in those places I'll start sweating a LOT, having problems breathing, getting hot flushes, lightheadedness, feeling like I might puke or faint, headaches, hands shaking and a general feeling of being about to pass out or loose control.
3) After those episodes (namely, when I get out of the said places) I start to shake all over, getting cold sweats, freezing hands and feet and it takes about 1 to 3 hours to get back to normal. I notice that I am also very anxious during and after this episodes, it gets better as soon as I manage to calm down.
4) I got my blood/urine tested and it's all right, except for a little alteration in the thyroid hormones - could this be the cause?
I am a healthy person, no history of any diseases in my family, the only medication I take is the birthcontrol pill, I'm normal weight and there's absolutely no possibility of being pregnant. Has anybody got a possible diagnosis? And what can I do to improve my situation?
