if the sore throat continues, go to a clinic to have your throat looked at and a throat culture. Are you having and fevers or chills?
You don't say what color the spots are - white spots are caused by vitiligo or tinea versicolor.
Dark spots are caused by old age or too much sun. Sometimes they are caused by pregnancy. (melasma).
