I burnt my throat

By drinking tea with a straw and not realizing it was that hot. Actually it was "Yerba Mate" and a "Bombilla". I am sure that's the cause because the thing was pointing in that direction of my throat and I felt the burn the second it hit. Now a couple days later my throat still hurts and looks like a blister/cankersore thing behind my tonsil. lol feels like one too, like if I eat/drink something that would normally irritate a cankersore, it irritates that thing. Hurts when I swallow, it's not a regular sore throat figuring something cold like yogurt or even icecream (yeah, I had to try it) doesn't "soothe" it.

And no, I couldn't go to a doctor if I wanted. No health insurance.

I'm gargling with salt water. What else?
