I am a 39 yr old smoker who has had GERD, IBS and anxiety issues for many years. I take nexium daily for the GERD and metamucil daily for the IBS. I am not on any anxiety medication. About 5 years ago I had an upper GI endoscopy that came back fine. 4 days ago I woke up with terrible pressure in my chest. I have had this before with my GERD but this was the worst it had ever been. Since then, the pressure is gone but I have had very strong pains when I swallow or even belch. Basically anything that stretches my esophagus causes horrible pain. I am not sure what to do and I can't afford a doctors visit. Does anyone have any advice? My anxiety is really starting to kick in and I am beginning to worry about tumors. How long should I wait before I should really worry?
