Hi sir/madam, I am suffering from cough and cold from past 8 to 9 months.. usually around morning 3 to 6 am i feel more tightness in the chest and this is not the daily case. I am allergic to house hold dust. But many of the  times runny nose, which eventually causes cough. My phelm is light yellowish in colour. I used to take Homeopathic medicine six month back, and it worked very well for me, but my doc has moved away and I need to look into another one.
