I had nose bone surgery as bone was deviated but now I am again facing difficulty in walking, breathing as I feel cough is there and doesn't comes out as one nose is blocked, but now my condition has worsened as after brushing teeth I vomit daily, as well as after eating anything I feel like vomiting and around 60% of times I vomit. I have reduced eating, all the time I feel heaviness in head , nose and feel that something is stuck in throat. I got cold this week and now I cannot breath properly as well as cannot eat , cannot walk fast ,of I do so I vomit and water ,food everything comes out... My condition is worst, please suggest which specialist doctor should I consult, and what is the reason behind all this , what should be the next course of action??
