Hi,I have diagnosed cold-induced asthma currently living in FL but went to cold CT for 4 weeks mid- Dec. through mid-Dec. my asthma flailed up and spent all but 4 days in bed during that 4 weeks. Back in FL now but still feel tired, coughing and heaviness in chest. I have a nebulizer, max air, and advair, also take singulair. Have also had blood work and recent X-ray , both came back negative. Any suggestions?
