Hi, I have this sensation of tightening of my throat (as if there is a lump there), at the lower part of the throat, since yesterday after a meal. I can still swallow but it seems like even water and saliva have to get pass that "lump" to go into my stomach (I am sure I am not imagining things). This throat irritation started with a cold feeling in my throat yesterday followed by the tightening feeling today. I feel like I cannot breathe properly too. Please could you advise on this?
