I am 13w pg with DC2 and am experiencing discomfort bordering on pain at my cs scar from DD (4). It's made more strange by the fact that the whole area has been numb since my EMCS with DD but the pain feels like it's coming from the inside.
I had an Emcs with ds (now 4). I too have a numbness in my tummy And down to my scar. (Now 34 weeks pg)
I have had a pulling feeling at one end of my scar which does not particularly hurt but is uncomfortable. When they stitched me they did it a bit squiffy and skin is a little puckered so I've always thought mine was just where the skin was stretching at this point.
