How To Treat Discomfort In The Throat And Gag Reflex?

About a minth ago i swallowed a shrimo from shrimo cocktail and there was a piece of the tail. I btiefly felt as though i was choking but coughed and some came out. My concern is that ever since then i feel that there is something still stuck in my throat. It is causing some discomfort and my main concern is possible infection as well as irritation which is causing my gag eflex to kick in and causing vomiting. I have been so busy with the holidays and work that i havent made the time to go to the ER as I do not have a general practitioner i see regularly. Any insight to a course of action i should take and what said course ofnaction might entail would be extremely helpful i am anxious and afraid to go to the ER as im afraid its something more serious than a shrimp tail stuck in my throat. Thank you for any insight and advice you may be able to provide it is greatly appreciated...Jeanna
