Hi, yes I've experienced that same pain. Even when I'm not sick and haven't been coughing, if I'm sitting just right and maybe cough a little, the pain across my stomach is nearly unbearable. Makes you want to curl up in a ball and never move again. I had two c-sections, one in 1999 and one in 2002 and to this day I still have that issue. My doctor says it has to do with damage to the muscles during the c-section (along with overall weak muscles in that area).
