It was about the 3rd day after burial.
 
The swelling was even from the first day.
  
I had it look like an inner twin, but one side was swollen because it was covered by the inner twin, but the other side was swollen like a semi-line so that the entire line was visible.
 
Are there any cases where the swelling was uneven after surgery?

I wonder if the lines will become more even as time goes by, or if they were patched by surgery.
 
I just wait for the swelling to go down as soon as possible.
