Acid reflux or leak?

[bgeb 24]

I am 9 days post op today. Last night at about 11:30 I woke up with pressure in my chest, I could taste a off taste just by breathing. I had an urge to cough, when I did I felt the need to spit up. It was yellow stomach acid, small amount. I walked around a bit coughed and a bit more came up but was relieving the best pressure. I made a cup of peppermint tea and got back into bed, nauseated feeling subsided and I slept at a 45 degree incline til4:30 when

I woke up not near as bad as before but slightly nauseated. Tis time it just felt like a little heartburn. I took my Prilosec. I had posted what was going on with me last night on my fitness pal and had 2 people communicate to see Dr for possible leak. What other symptoms might I have with a leak? I have never had acid reflux, what are those symptoms? I have been feeling great til now, no pain meds, great energy level, no fever. I plan to call Dr this morning after office opens but would be grateful for your feedback.
