hello, hye. i am a 19 years old girl. i am 157cm high, and im not quite sure of my weight, perhaps around 70. i am allergic to dust and dirty water eg: puddle. my house is under renovation, so i always meet the doc to take some medicine from them, because my dust allergies is unbearable. since last saturday, i have this very weird burning sensation from the bottom of my neck until the middle of my chest . it really hurts, and sometimes i feel like there is something stuck there, i feel like choking with something. i tried burping, but didnt succeed. i also end up vomiting my food, so that i the pain will lessen. im not a heavy smoker, but the last time i smoke was for a week on February.
