Hi, ive been having this problem for a few days now and it is causing me to just want to sit down all the time. I feel very dizzy all the time, my head feels like there is a balloon being blown up in it, when i blink and swallow i get a weird sensation throughout my body (not a nice one), i feel physically sick all the time and i cant stop eating, im not sure what it is but i do have an under-active thyroid and i am medication for it, i am 17 and female. Please help.
