Suggest Remedy For Thrush And Canker Sores On Tongue

Ok, so I woke up about 2 or more weeks ago with a pure white tongue, I tried taking off the white stuff but only some came off, I immediatly googled it and what came up was thrush and I thought I should see a doctor so I did. She said I might have a little bit of thrush and to take these pills for 2 days and to eat more yogurt. So I have been but I noticed 2 kanker sores or however you spell it were on each side of my tongue, didnt think much of it, I was more worried about the thrush. I still have the thrush now but the kanker sores hurt and are now white and look like zit (but not one) and the white part is falling off but it wont come off, it looks like part of my tongue is gone where the 2 kanker sores are. Also my tongue has bled 3 times when I brush it since that one morning. What should I do? My tongue feels so weird since then..
