I had a c-section and it did itch like crazy. However, I didn't scratch at it too much and instead would take to a semiwarm shower... so as too alleviate that itch, the other thing you can do that helped me was to put RAW Aloe Vera Gel on it OR if you have plant or know someone that does, peel back a leaf and apply. it's very soothing .. work for things that itch and also for sunburn. Anyway, I will say that it's been 9 years since my c-section and I NEVER regained complete feeling where I was cut. Oh I can feel things slightly but never the full on sensation I once felt.Therefore, don't be surprised if that aspect never goes away.
In the meanwhile, get some PURE Aloe Vera Gel from a health food store.. make sure it's 100% pure (no additives) therefore, it won't be with the creams.. it will be with the LIVE foods in that section.. apply it and see if it helps. I like to put it in the fridge .. this way, it's nice and chilled when you apply it..
best of luck
