Hi doctor, I had a viral fever 3 weeks ago associated with dry cough. I was on antibiotics for 5 days. No fever now but cough is not going at all since 3 weeks. I'm on homeopathy medication but it's not helping. I have a history of allergic bronchitis which happens with almost every season change and doesn't go for at least 2 months. I've even taken steroids in the past for cough. Pls suggest some good medicines for me.
