Hi your symptoms suggestive of dependent edema where in your heart s failing to work normally which causes pooling of blood in limbs...consult physician or cardiologist for further examination and work up

hello. swelling if feet is called pedal edema. I suggest you go to a doctor and get your blood pressure checked out. these kind of complaints are common in hypertensive people. ECG and ECHO will also be needed to rule out other causes and arrive at a proper diagnosis along with clinical examination. additionally you can put a pillow or two under your feet while sleeping. but consult your physician ASAP. regards.
