What is the best thing for a sore throat? I have a cold and it's probably related to my sore throat.

For a sore throat, the best thing to do is to reduce the amount of mucus in your nose that may be dripping down your throat. You can use a product like Sinus Rinse™ twice a day. In the meantime, you can try taking Tylenol™, Advil™, and warm honey to help alleviate the pain. If your sore throat persists for more than two weeks, it would be a good idea to see a doctor.
