burping to relieve pressure / tightness in chest? Pre and post OP

Apparently it takes a few months to "unlearn" the habit of swallowing air. If you are having trouble with it post-op esp if you can't burp, try to be really mindful of how you are eating and breathing. Make sure you're not chewing with your mouth open or rushing meals, don't use straws or drink bottles that have the sports cap (the one like on commercial bottles of water) because that introduces more air and of course you shouldn't be having any carbonated beverages anyway. open mouth breathing can do the same thing, I've been catching myself doing it a lot more than I thought I did since I've been paying attention.
