Try drinking чай with honey and lemon. If that doesn't work, some throat drops and maybe a little Robitussin will help. Hope Ты get to feeling better:)
depends on the cause, if its because of a cold, try something warm, like tea. if its because Ты overused your voice yesterday, try gargling salt water. but if it feels like a stabbing pain, Ты should probably see a doctor, Ты may have strep throat and will need medicine for it.
