Hi, I have chest congestion with little phelm (light yellowish colour). This happens during early morning around 3 to 6 am. I am allergic to dust, if I am exposed to little bit of house hold dust I will have cold/runny nose. If I have runny nose eventually cough will follow. Please help me on this. I used to take Homeopathic medication sir month back, which worked like a charm. But doc has moved away from the current location and now I need to switch to.another one.
