I have been fighting bronchitis for about a week, including minor post nasal drip. Have been taking a Zak pack for 2 days and all of a sudden i started feeling like something is lodged in the upper part of my throat causing my gag reflex to go crazy leading to intense dry heaving for 4-5 minutes every 10-20 minutes, been going on for about 4 hours now. Have tried hot tea, eating dry bread, etc. to loosen or break loose what ever is causing the issue. I didn t swallow any foreign objects and haven t eaten for 3-4 hours before this started. Should i go to the ER?
