Why is the mosquito bite on fingers whether hands or feet are more painful? Itchier?

that cos your extremities receive more blood due to more movement. and with more blood, the sensors in your skin become more responsive. hence, becoming more itchy.

To stop Mosquitos bites from itching your kent to just forget about them and thryl will stop. But I guess if you use your hands alot they become more iritated as hey are in the way. You should bandaid them so they do not blister
