Hello there. Since when does he have such a problem? Does it remain swollen throughout the day ? As of now, you can do foot end elevation by placing pillows under the legs while you sleep. What this will do is push the fluid in the direction of the gravity. Avoid tight foot wear, socks, clothing etc. Consult a physician in person for further evaluation. Regards
