I had my surgery 12/12 as well.
The dry heaves is the Worst!!!! It seemed constant for me until after I got my swallow test and they gave me some magic meds to take it away.
I've been in pain, but my Dr. had his patients up walking after surgery. We had to do at least twenty laps total around the hospital wing.
Walking makes the pain feel a little better. It helps prevent blood clots, but also will move the gas around if you have any. Walking has become my best friend in relieving pain other than pain meds.
I have 3 incisions and one incision for drainage total 4. The one on the right is very painful as that's where the majority of the work was done.
It hurt so bad I couldn't even move after surgery. I sleep sitting up elevated by pillows and when I'm in pain between meds I walk.
You said your eating yogurt? I'm on Clear Liquids the first 3 days don't know if that could b making your pain worst.
