Sore throat relief

I believe I’m either having trouble with allergies or I’m possibly sick I’m not completely sure but my throat has been feeling inflamed and sore for the past couple days. It gets worse when I sneeze and feels bad when I wake up in the mornings too. I’ve also been coughing a little, my eye are dry which is normal for me, and my nose feels a little stuffy. I also have some phlegm in the back of my throat. I tried taking medicine but it didn’t help much what else can I do to help relieve these symptoms?
