every so often, out of the blue ill get this feeling as if someone stabbed me in the back of the troat with a sewing pin and then that whole area, probably about an inch around, will swell up and i cant talk and its almost unbearable for a few seconds. it makes my eyes water and everything. my throat only stays swollen for a few seconds but it goes away faster if i drink something. this only happens a few times a year usually but it happined twice tonight.
