I do too. Its an odd mix of numb in some areas and tender in others. I'm just over 6 weeks pp
This will also be purely because you were pregnant, never mind the C-section. Your skin/muscle/tissues are all suddenly shrinking back down, it's normal for it to feel tender for a few months.
I'm 8m pp and still have times it's tender, now that the feeling is mostly returned
Yes I did and I still do 4 months later, I think it's normal
