Hello, According to the mentioned symptoms, I suspect a pulmonary pathology like asthma, COPD, allergic bronchitis, eosinophilia. Achest physician can arrive at an accurate diagnosis after clinical examination and required investigations. One thing I can certainly tell is that Pamelor is in no way helpful for treating chronic cough. To those patients who visit my clinic with such symptoms, I do order the following investigations only after a thorough and detailed clinical examination: 1) chest x-ray PA view 2) sputum examination 3) absolute eosinophils count 4) pulmonary function tests. As you had been to so many specialists, I can understand your pain. Just once see a chest physician once and discuss the above issues. Now I can suggest few medications that would provide her a temporary relief: 1) if it is a productive cough, expectorant syrups containing bromhexine, guaiphenesin can be used 2) for dry cough, antitussive codeine containing syrup is useful 3) a bronchodilator short-acting beta 2 agonist spray inhalation would help in relieving shortness of breath. 4) exposure to trigger factors like cold environment, dust etc to be avoided. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Pallavi.m, Anesthesiologist
