The itching is a good thing, it means you are healing. Holding a pillow over your incision is a good thing when you get up or when you cough or sneeze. It's called splinting and it will not only be protective but it will help with discomfort when you are doing those things.
As far as your staples are concerned, I always tell my patients that if there is any pain at all, it usually feels like plucking your eyebrows. Most don't have any pain though.
i was lucky and had no drains or staples, just glue, but I did end up with an infected incision.
I am a month post op and I can finally say I feel like I am healed. No more scabs no more drainage, just kind of scar tissue that I am hoping will reduce with time.
