What Causes Sick Feeling And Breathlessness After Taking Cortisone Shots?

I have had bronchial pneomonia for which antibiotics were prescribed. I was also given a Turbuhaler to use twice a day and cortisone injection. After two weeks of this illness I felt better and had to go for innoculations for a USA visa. Polio, and influenza were injected. I became worse and went back to doctor who presribed a stronger antibiotic and cortisone injection. Two days later I felt very sick and had difficulty breathing. I went to the hospital emergency unit and was put on a cortisone steroid drip and given nose drops, analgesic, cough mixture, cortisone steroid tablets. My cough went from dry to wet and phlem is coming out. I am also experiencing the pins and needles when i cough. Am i healing because its now been four weeks?
