Yesterday and today I noticed that i cannot eat w/o major discomfort in my esophogus. It almost feels like food is getting somewhat stuck and it hurts around my breatsbone. This happened after a nasty cold/flu thing that caused major drainage to the point of almost choking several days in a row. Could this be causing that raw discomfort down my throat, I have been coughing too. I'm really scared thinking its throat cancer or someting horrible. Has anyone had this recently, can post nasal drip cause your throat and stomach to be sore? Please someone help me set my mind at ease!
