2. Redness in the Throat
Another sign that your sore throat may be caused by strep is that the throat will become red. If you look at your throat and it is red in color, it may mean that you have strep. The throat may also have some mild patches that are visible on the tonsils. When you have strep throat, often times the tonsils will appear very red or have patches of red and become quite inflamed and swollen.
If you have difficulty seeing into your throat, ask a friend to look at your throat for you. Use a spoon to help keep your tongue out of the way while you are trying to get a good visual of your throat. If your throat is very red in color, it is likely that you have strep throat. A doctor may be able to prescribe antibiotics to help clear it up.
