Yes i have that I've only had 1 c-section I always just thought it was ligaments stretching from the pulling of the sneeze or cough, I never thought of it as an issue or anything just thought it was normal
Ask your doctor about pain from adhesion or google it.
I don't remember having this problem last pregnancy & my scars haven't hurt for a while (last baby was 3 years ago). Although I did have a miscarriage & d&c in April.
My mom had an emergency c-section with her last baby. I haven't had this issue as to this is my first pregnancy, but if it helps any when my mom had hers she had that problem with coughing and it hurting her and she still does from time to time. But I would maybe ask your doctor to be completely sure hun!
