what could it be when you get anxious for burp and feel a thing swelling just right down you re left side rib?

Answer 1

looks like hiatus hernia.
It is basically protrusion of stomach through diaphragm, your breathing muscle which also separates chest from tummy.
As the you try to burp, the stomach contents (mostly air but sometimes juices which give you heartburn) come out via mouth.
if there is any herniated stomach, it might swell due to entry of air into otherwise collapsed segment.
I would try and see the doctor asap as although they are not that dangerous (like the more commonly known hernias) but its better to get rid of them sooner than later.
Ultimately for all that you know it might be nothing and that might be reassuring in itself

Answer 2

sounds very like a hernia - its not dangerous in most cases but you should get it checked out. If it becomes more bothersome or painful as they can sometimes, there is a simply medical procedure to sort it out. Otherwise drs often encourage you to put up with it as it doesnt cause immediate concern. Get your GP to check for you.
