Why are scabs so itchy?

The reason they itch, is that there's a lot of healing activity going on in the area. As you say, all it takes is some restraint not to pick, and to be aware of what you're scratching when your hand strays to the scabby area :-) There are ointments you can apply to the area to relieve the itching - a band-aid isn't great, as it will make the area softer, and the scab may fall off prematurely. The body works in the most efficient way possible, so it's not concerned with how much we want to scratch. There are lots of tingling nerve-endings on the skin, especially when new skin is emerging - that's just life and nature I'm afraid! It's not that hard to not scratch, with a bit of willpower!

I know what you mean. It is sooo annoying. Sometimes i will keep a bandaid on them, but it doesnt stop the itching. There should be a wonder cream that heals them straight away. Best wishes to you, kythe

I think scabs are like a cast on your arm. The skin under your scab is dry and gets itchy just like your skin under you cast gets dry and itchy. I am just speculating here but that is what came to my mind just now. I do not get many scabs nowadays but when I was a kid I had plenty. My younger sister used to pick at her scabs and eat them! Gross! but she was little then. I do not believe she does that any more. Sorry sis, your secret is out. But that is what brothers are for. :) lol!
