When I use my hands, not on the phone for scrolling or typing, but for brushing my teeth, preparing food, that kind of thing, my fingertips tingle after. Sometimes it's down to the first joint on some fingers. They don't change colour. Sometimes it starts during the activity, if I'm doing it for long enough. It feels like a tiny version of pins and needles, like you get in a foot you've sat on. I've had it for a few months now. Each time it takes a couple of hours to pass. It's unpleasant rather than painful. I don't get it in my toes. Does anyone else experience this?
