### Patient: Doctor, I have been experiencing some coughing, nailbiting, difficulty breathing, anxiety and nervousness, and chest tightness. What could be wrong with me?
### Doctor: Based on your symptoms, you may be experiencing Hypertrophic obstructive cardiomyopathy (HOCM), which is a condition where the heart muscle becomes abnormally thick, making it harder for blood to leave the heart and potentially leading to symptoms like cough, nailbiting, difficulty breathing, anxiety and nervousness, and chest tightness. We'll need to do some tests to confirm the diagnosis and determine the best treatment plan for you.
