I had a c-section over 2 years ago. Lately I've been getting loads of lower back and abdominal pain, much like bad period pain. Last night I was rubbing my stomach and felt a lump at my c-section scar area. How can a lump suddenly appear after 2 years? I've had cysts come and go on my ovaries, could it be another cyst? It's small, about 1cm, feels like a hard pea and it's actually slightly underneath my scar and i have to press in to feel it fully.
