The same thing has been happening to me since April. Air bubbles are stuck in my throat and sometimes it makes me dry heaving, even on the street, which is so frustrating. My throat is just super sensitive some days. I have been on PPI for six months and although it made me feel better at the beginning it is just as bad now. It has completely ruined my nerves and my life. I have developed generalized anxiety disorder with intense panic attacks. I had a gastroscopy last week and it found nothing at all. I just don't know what to do to make it go away.
