I've never had reflux..... no idea what it feels like...... how can I tell the difference between the pains I'm feeling? (5 days post op) stabbing pain, waves of abd pain , muscle pain, soreness....

Everyone is different but I would say those are gas pains. Reflux for me is more lingering pain or a burning sensation in my chest/throat. Try to walk as much and often as you can. Gas pains get better with walking.

Doesn't sound like reflux. You'll know that if you ever get it...and I hope you don't. The burning in your throat and chest is awful with reflux. At time it makes you feel like you're going to vomit. I agree that your pains sound like gas but you need to consult your doctor if it keeps up.
