What is it (or what is it even called) when you can feel an itch inside your limb but can’t reach it? Scratching remotely close to where I think it is doesn’t get it and I sometimes resort to lightly slapping the area to “scratch” that itch. Is it a nerve that’s firing off the wrong signals? If I’m lucky I can scratch all over and one random patch of skin will scratch the itch of whatever’s inside my muscle or limb even though it’s nowhere close.

Phantom itch doesn’t sound like it but I’ve no idea what this is even called because I can’t figure out the correct sequence of words to accurately search this!
