I am getting Dry cough repeatedly for more than a year and I have consulted a General Physician few months back and he suggested Antibiotic tablets for several times. Still the problem is persisting, I will be alright while taking Antibiotic tablets, within a week or later, I will get into trouble again by getting dry coughs. Doctor said it might be due to Lung infection or Respiratory problem. MX test and Blood test result seems to be normal, there is no presence for TB. And I would like to know who will be the best person to approach ???
