OK so I am 30 almost 31 weeks pregnant and with my last baby they did a c section and where the scar is on the skin right on the coner of it is reaaly sore and they are a bump that hurts reaaly bad this happened right after the surgery but went away and is now back what can this be?

I had that same bump after my c-section on the right side also. My doc explained to me that when they are done stitching you up inside, they have to tie a knot somewhere, and a lot of times a women's body rejects the knot, causing a little bit of infection. I would call the doc though just to be sure that everything is OK, and that it is not anything serious.

OK thank you I am just worried becosue it is on the scar going on the outside from left to right and they had to to a classical c setion so on the inside I am cut up and down

Have you called your doc? If not, you might want to just to be safe.
