I had my second c-section 9 weeks ago. It was straightforward and I didn't have any problems afterwards. However I bent down to lie on the floor this morning -looking under the sofa for missing toys - and got a sharp pain under the left hand side on my scar. I'm now getting it when I'm moving around particularly going down the stairs. It feels like something is tearing although it looks fine. I didn't have this after my first section. Is it normal or should I get it checked?
