I had surgery on 6/19 as well. I stayed 2 nights in hospital & was sent home nausea, reflux & pain meds.
I took pain meds for 2 days & did very little walking. Was only in pain when used stomach muscles.
Today, 6 days post op & I ate my first soft meal, I’m running errands & driving. No problems. I’m a little slow paced & there’s still discomfort but nothing like ur describing.
I would call ur dr if I was u.
