20 days post op Tummy Tuck, super painful swelling. Any suggestions? (photos)

Hello there, thank you for your time. I am a little concerned I might of done something as the middle of my stomach above my incision under my belly button has become super swollen and painful, it's also kind of squishy. I choked on some food and ended up coughing very violently for about 20 seconds or so 3 days ago and have not been feeling well ever since. I'll post some pictures so you can see. Its difficult to try and take a picture of the swelling of course.
