Back in April 2007 my doctor replaced my usually Puffer with a turbohaler, during the rest of the year my asthma got worse, it was put down to stress at first but when I was put back on the puffer in Feb I felt better straight away. However I now have Oral Thrush since feb and doesnt seem to be dissapear. I have tried Penacilin and other tablets that you can only take for 2 weeks. Any advice!!!
