Thank you for responding, pamseyflower1, and sorry for the huge delay. I experienced really bad pain right under my boobs in my upper abdomen. Felt the pain go through to my back. I had to sit up because the pain was so bad. Asked for inhaler because I thought (desperate to get rid of the pain) it might be a bad asthma attack, but because I had not brought any, they could not give me any. I could not go back to sleep for a loooong time. It was so bad, I thought I was going to have to rip off the wires and go home. Does this sound like pain from aerophagia?
