Possible sinus infection or beginning of strep throat?

Me

I started feeling kind of sick sometime this week. I have this pressure in my head that won’t go away but seems to be relieved a little when I close my eyes. I also have a sore throat that feels a little swollen and the outside of my throat (neck area) feels tender and sore too. My nose isn’t stopped up but does feel a bit stuffy. I know I’d need to go to the doctor to be sure but don’t plan on doing so unless it gets worse.
