Sometimes, home remedies are not enough. If pain or swelling in the feet persists for more than a few days, it's time to seek medical attention. Intense physical activity or standing all day are common causes of swollen feet, but if rest and relaxation do not alleviate symptoms, a more serious issue could be to blame. Deep-vein thrombosis, heart failure, and kidney disease can all cause swollen feet, but individuals with these conditions may be experiencing other symptoms, as well. Diagnostic tests can determine any underlying cause.
