I'm really worried about this chest congestion I've had for the past 34 days, along with a dry cough. It started with wheezing, a bad backache, and shortness of breath, so I took the meds my doc prescribed, Lcin 500 and doxovent 400, and I've been nebulizing myself too. The symptoms are a bit better but the cough is still hanging around. This same thing happened to me 1.5 years ago during the winter. Is it just the cold weather causing this, or could it be something more serious like asthma? I got really scared after googling these symptoms. Does having wheezing and a dry cough definitely mean it's asthma?
