This is Kitt and I am on loan to the GERD forum as one of the active moderators is off on a much needed vacation.
Each day will be better but you are going to feel all sorts of weird sensations/pains as things start to heal. Around Day 4 is most likely when you first began to notice the swelling at the surgical site and this usually continues for 2- 2 1/2 weeks.
Before surgery were you having any breathing problems or do you have a history of asthma?
Most surgeons will tell you that with this surgery you will not burp - hiccups do happen.
To be on the safe side I would visit your Dr. re you chest sensations because you are also having SOB issues.
I will be checking back to see what your Dr. feels is going on.
