My daughter has been twice to her doctor - the first time diagnosed as pharangytis and prescribed anti-inflammatory tablets and medicine and told to boost her immune system with propolis, royal jelly and vitamin C. She has a coating on her tongue and what seems now to be an enlarged tonsil and mouth full of mucus on waking. Last week she developed tiny splits on her inner cheeks which healed by themselves. She revisited the dr as she was worried she had thrush in her mouth. Her dr said no and gave her no treatment. This has been going on for a month now and although the soreness of the throat has gone she has developed a cold and is fed up of the coating on her tongue and the mucus. Can you suggest what she should do and what it might be?
