Getting breathlessness while sleeping with swelling of feet is an indication that you may be having early symptoms of left ventricle failure or say heart failure. But with the history of asthma, you must mention at what age you started having asthmatic attacks, any precipitant factors of asthma, on what medications you are, and do you have a history of hypertension. You must proceed with your routine check up, blood pressure and blood sugar evaluation, ECG and chest x-ray. Sleeping in a propped up position may comfort you. These symptoms should not be taken lightly, and proper evaluation must be done.
