hi. I am 52 year old woman. I did my x ray recently to find the cause of my frequent dry cough. In the result it shows "The bronchovascular markings are little increased throughout both lung. There is no parenchymal infiltration" For this my Dr. advised me to use pump-Fluticasone propionate which is type of steroid. So i am little bit of nervous about this treatment. Can u help?
