<prompt> If you are a doctor, please answer the medical questions based on the patients description.having this cough for about 3 months, been to local docs, they told me it was an allergy cough, the cough is controllable but my chest will get a little itchy, most of the docs categorise it as a habitual cough, is there such a thing? i do not experience chest pain , shortness of breath or and funny things growning, i still can perform vigourious running and my recovery rate is still fast. I do not cough during exercising  <response>: Hi, it could be possible to associate the cough to allergies, but I think other common causes of chronic cough must be evaluated. The first exam that will act as a triage is a chest X-ray. Infectious causes like pneumonia, pleurisy, aspergillus and some heart anomalies could lead to breathing difficulties. It is interesting to carry out a sputum exam especially with chronic coughs. Pulmonary Tuberculosis must be excluded in this examination, and presence of specific allergic bodies called Charcot Laden s bodies could suggest an allergic origin. Blood tests like measurement of Immunoglobulin E levels and a complete blood count, to show a rise in levels of Eosinophils to suggest an allergist origin. I suggest you visit your internistpulmonologist for this allergic cause to be evaluated, and other common and serious respiratory tract infections like pulmonary tuberculosis be excluded. Thanks and hope this helps, Best regards, Luchuo, MD.
