I have swelling in my throat i can't drink anything i throw it up right away. i'm also throwing up foam. what's wrong with me?

Why are you waiting?: With symptoms like these, you should be getting seen by a doctor. This could represent a serious problem.

Concerned...: Your symptoms are potentially concerning for either angioedema or esophageal obstruction. Angioedema is a allergic reaction that can cause swelling of the back of the throat causing soreness and difficulty swallowing. Esophageal obstruction could be caused by a foriegn body lodged in the esophagus such as a bolus of food or pills. Both warrant urgent medical attention. Good luck.
