“Sore Throat ”

I woke up yesterday with a dry throat. I felt fine except for my throat feeling dry all day. I drank plenty of tea, water and had lozenges. Today I woke up with my throat hurting and my nose is a little stuffy. My throat is not hurting a lot but it’s enough to be uncomfortable. What can you recommend? I did take Advil but do I need a prescription medication or what works over the counter for sore throat and stuffy nose. I also do have a little post nasal drip. I never know what to buy at the pharmacy.
