Hello! Welcome and thank you for asking on HCM! I passed carefully through your question and would explain that it is necessary performing a comprehensive differential diagnosis between different possible causes that may lead to this clinical scenario: a lung disorder, an allergic reaction, a metabolic disorder, an infection, etc.. Coming to this point, I would recommend consulting with your attending physician for a careful physical exam and some tests: - a resting ECG - a chest X ray study and pulmonary function tests - complete blood count, PCR, ESR for inflammation - thyroid hormone levels for thyroid dysfunction - blood electrolytes - an abdominal ultrasound - a urine analysis - allergy tests. You should discuss with your doctor on the above issues. Hope you will find this answer helpful! Kind regards, Dr. Iliri
