I have been diagnosed with asthma. The dr. prescribed prednisone, & Advair, but I developed severe symptons of bone & muscle pain in my his & legs, severe headache, ear pain, & back pain. When I coughed, Iwas bringing up pieces of Advair that did not get absorbed. I stopped the Zyrtec last night, but needed only one dose of Ventilin, & Nasonex today. Last night I coughed long & hard, & finally brought up mucus. My chest & body hurt from all the deep coughing. This afternoon, I noticed that the color of my urine changed to a tea-color. Can this be blood in my urine, & could it have been caused by the severe coughing? I have a little pain in my bladder when I urinate.
