<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been feeling a lot of anxiety and nervousness lately, and I also noticed that my legs have been swelling. What could be causing this?  <response>: Based on your symptoms, its possible that you have Hypertrophic obstructive cardiomyopathy HOCM. This is a heart condition where the wall of the heart muscle becomes thickened and makes it harder for the heart to pump blood effectively. The leg swelling is a result of fluid build-up due to the hearts inability to pump blood properly.
