Strep Throat or Sinus Infection?

I'm having trouble figuring out if this is strep throat or a sinus infection, as I know both have similar symptoms. I don't want to take an unnecessary trip to the hospital.

As far as I know, I have white on my uvula and tonisls, growing discomfort in swallowing, I haven't had a fever recently, no body aches, and haven't sneezed or coughed. My throat feels like a fire is trying start.
