(Concern) Is there any medicine that is good for sore throat symptoms?

I'm suffering because of the heatstroke from the air conditioning.ㅠ

My condition worsened, I caught a cold, and I also got the flu.

I took the prescribed medication a few days ago after the consultation, but I still have a sore throat.

I'm buying and taking Strepsils at the pharmacy~

I don't have a fever... Is there any simple medicine I can buy at the pharmacy?
