I've been having this pain swallowing for the past 6 months. It starts with me feeling that I need to belch and a few hours later it becomes very painful for me to swallow even saliva. This lasts for a few more hours and then gets better. Also, when it hurts to swallow I notice that I have an excessive amount of mucus/saliva. I don't have any symptoms for around 3 days to a week after it get bad but then it starts all over again. I went to my doctor and he's prescribed Nexium. I'm not too sure if it has worked all that well. I'm really nervous. I go back to my doc on Wed to get some more test results back. Anyone ever had this before?
