Firstly congrats on the safe arrival of your little boy Adam and I am glad that the c section experience went well for you.
I have had 2 c sections and although the scar is bigger this time around I dont have any raised areas over or under the scar area. It could be how they stitched you though as every doc has diff method and my scar looks better this time than the 1st time.
I would keep an eye on the wound to ensure it doesnt open but just ask doc at your 6 week check up
