I am suffering from dry cough since 4 months, i've had my urine, saliva, running and blood test done. I've taken all the prescriptions my doc had given but still I have no relif. He said I have li'll cough in my lungs. I do smoke tough but trying to quit. What should I do? Any home remedies would help? And i'm also having a itch under my testicles and beside them on the thigh and when I itch it there will be a small pimples there and it dosent feel good. Thank you.
