Does this sound like tonsillitis or strep throat?

I've had a sore throat for 3 or 4 days now, but no one took me seriously when I said how sore it was. This morning something didn't feel right, so I looked in the mirror, and my tonsils have big white spots on them and the right one is swollen.

I have a doctor appointment in the morning, but I have OCD so I wanna know as much as I can before I go in..

I've heard mixed answers as to whether or not strep throat will produce swollen, spotty tonsils. I've had strep throat once before, but didn't look at my throat in a mirror, so I don't know what it looked like. I know for strep, I'd be given antibiotics and sent on my way.

I read that tonsillitis can't be treated and they pretty much say to let it run its course.

Does it sound like strep throat or tonsillitis, or is the only way to tell a culture? Also, is there any treatment at all for tonsillitis other than getting tonsils removed?
