If you are a doctor, please answer the medical questions based on the patient's description.

### input:
Had an ekg with result of septal infarct, age undetermined and normal sinus rhythm. This was done because I have been having dizzy spells , often with constricted pupils and have had a chronic cough for two months. They took blood and did chest xray tlday as well. Have unexplained rash on trunk. Last biopsy at derm showed granulare aneuloma (sp). Have follow up derm next week as rashes have multiplied. Doc referred me to neurology with an mri, pulmonology a d cardiology. A little scary. What are they looking for? Possible lung disease? Had pneumonia this summer which turned out to be difficult to diagnose.

### output:

Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, they are looking for multiple organ involving disease like connective tissue disease (CTD). CTD s can involve lungs, heart, skin, brain etc. In lung involvement, CTD can cause fibrosis, bronchitis, pneumonia etc. So your chronic cough can be due to any of the above-mentioned lung pathology. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. Chest x-ray and CT thorax to rule out fibrosis and pneumonia. 3. PUT (Pulmonary Function Test) for the diagnosis of bronchitis. So better to first diagnose yourself and then start appropriate treatment. You may need antibiotics, antihistamines, inhaled bronchodilators and inhaled corticosteroid (ICS). Hope I have solved your query. Wish you good health. Thanks.
