Prednisolone for Lung infection treatment

I have a mild pneumonia (am asthmatic) Since I am allergic to penecillin, the pulmonary physician Doxam retard had prescribed 10 tablets. But every morning I got less air and on the 6th day I had to put down the tablet. Early in the morning I thought I had a marble stone on my chest. In addition, I was prescribed Prednisolone 10mg by Doxam I also got oral fungus and the prednisolone I am as shaky as an alcoholic. I have to say, however, that I have already taken 14 tablets of Avalox. Since I dropped off Doxam, I’m getting good breath.
