good old fashioned anxiety could cause these symptoms. However, the only way to know that you are okay is to get checked out. GERD is also flared up by anxiety. Anxiety puts a heavy load on our adrenals and all of the nerves in our body and our body has to reflect what's going on somehow. Do you do deep breathing exercises when this happens? Do it for 20 mins and see if is still happening. If it just anxiety and you do the very steady and deep breathing it should go away -- at least for a little while. If it doesn't all the more reason to get checked out.
