Misdiagnosed throat growth

[jjkkll]

I developed a painful throat on swallowing over a week ago, a white ulcer (not a white spot, an ulcer a.k.a canker sore) on my tonsil, about the size of my baby finger nail. I went to the doctor and he said I had tonsilitis and gave me a 7 day prescription for clarythromycin. I have finished these. My canker sore did not get smalller, it got much larger (larger than my thumb nail now) and changes colour every day, from green with red spots to white and brown. Behind my canker sore I have seen what I presume are my actual tonsils, but there's two growths, one large the one above small. There is a white pattern on these with brown spots in the middle of them.  There is not much inflammation but there is redness. There is horrible pain on swallowing. Help please.
