Avoid any irritation: if it's not painful and doesn't itch, you probably don't have to take any action. However you do need to avoid scratching a plane with it. Avoid any kind of friction.avoid putting any substance or chemicals on it. If it's just a simple mosquito bite, pimple should go away on its own. Give it another week if it's still not bothering you.
