Easy sore throat question ?

ok so around tuesday i started to get a sore throat i started drinking alottt of water and washing my hands alot and then wed thursday it stayed the same friday it got worse but bearable and same today its alittle worse. i dont have a runny or stuffy nose. im a little cold but its winter and i dont have socks on lol. i do swim every day so i figure yeah im going to get sick. i have cough drops alot so it helps my throat and i try to have alot of cold milk with my cereal. so i guess my question is how long is this going to last and doesnt call for a doctor right
