How Can Tonsil Swelling With Diarrhea And Pain Be Treated?

Hey, I woke up this morning and it hurt to swallow, after checking it out in the mirror, I noticed that my right tonsil appears to be much larger than the left one. My only other symptom (they are hard to determine because I was drinking last night) is diarrhea, I guess all I'm wondering is how to make the swelling and pain go away
