Hi I m Chetan Sharma. I am 29 year old. 1. I have pimple on my upper back and below neck portion since 5+ years. I have took allopathic medicine 4-5 times already with full course. From beginning I thought they are from young age Harmon change but after 2 - 2.5 years u took medicine of that and took for long time but they reduce but not completely gone. So please suggest. 2. From same time interval I have always some cough and little bit dandruff type. Not exactly dandruff. Please suggest.. I have already took allopathic medicine as well as himalayas, selsun, head and shoulders as well as lots of shampoo.
