Evil mouth

So today my mouth still hurts like hell. I tried difflam and paracetamol to no amend :( I then decided to call the dr again to see if there was anything else that could be done. He asked if I had a coating on my tongue (I do) and said I have oral thrush (why had no one else thought to check for this?!) so has prescribed me a mouth wash to cure this (fingers crossed). I'm cross that the hospital gave me any old mouth wash without checking my symptoms. Especially with the pain I've been in! But hey ho! Still no caphosol but hopefully the pain will go soon - it's horrible :(
