The other comment explains the itchy part but the really interesting part is the relief. Itching is a sensation which your brain only thinks about with a low priority. That’s why if you take your mind of it it stops being registered. Scratching basically creates a bit of pain, a very tiny bit. And this sensation of pain, even if it is very light, has a very high priority. That’s why if you scratch, the signal of scratching overlays the itching signal, and with this blocks it out.
