question: in the last three days i have started burp/hiccupping all day long and when i need to burp but can't its like the burp gets stuck in my chest and it hurts really bad, it feels like i literally have a lump in my throat.  the first day i had it, i also had heartburn but now the heart burn is gone but i'm still burping? any suggestions? i'm a 28 yr old female taking 20mg of lexapro and 7.5mg of buspurone a day. thanks in advance!!
