Hello... Please go and get that bump checked out. It's most likely scar tissue, but I have a friend who had c section and she complained to her Doctor for months about a few lumps, and he just dismissed it being nothing to worry about. Finally she had tests that determined that it was cancer. Just for your own peace of mind, do get it checked and don't let the Doctor fob you off without doing proper tests.
Wishing you all the best...hugs...Helen.
I have a few from my last abdominal surgery, about the size of an engliish pea. The dr. said they were from a larger stitch thread she used there. Once I found them I think I kept pressing and got where I felt them without touching them. I would ask my doctor what it was.Could be scar tissue or small adhesion too.
Probably better to ask about this in one of the pregnancy forums!
I have had a C-section however, and agree it most likely is scar tissue.
