My throat is extremely sore, swollen and it's very painful to swallow...HELP?!?

honey, ice cold water, gargling with salt water. That's for the throat pain, but really, with diarrhea for that long you should go back to the doctor, that's not healthy and could be dangerous, i ended up hospitalized from dehydration that nearly killed me. I hope this helps, but seriously, ask a doctor about that diarrhea
