Try putting lotion on it when it itches , I have had two csections and I still have moments where it itches really bad. The numbness never really goes away, I mean it's hard to explain. I have feeling there but it's not like the rest of my body. I don't like my scar being touched either , like my underwear or pants rubbing or if my husband accidentally touches it I flip!
I am completely the same way with the top post. Had my son a year ago and it itches sometimes but HATE when it's touched. I have some feeling but not a lot. Hard to explain.
Sounds like you get what I get after I have mine it's a yeast infection and your ob can prescribe powder for it to make the itch go away. After you get out of the shower use a blow dyer to dry your cut completely.
