I went to the doc after having a dreadful cold, it left me with a scarey cough and a rattle. Doc listened to my chest and said that although there was junk in there, the problem was with my upper airway and prescribed ventolin. It was magical, no side effects and within 48 hours the cough had subsided to bearable, the junk came up and my chest cleared. Doc said that around here the virus had come with a truly awful cough this year and they had been trying giving ventolin instead of antibiotics and finding it very successful.
