I have a problem with swollen feet. Actually, it's my left foot that swells really big and my calf. My right foot swells somewhat and my right calf does, too. I am a COPD patient, with asthma and emphysema with high blood pressure. My daughter calls my left foot "elephant" foot because it swells and leaves a big roll where my foot bends.
I don't eat an exorbant amount of salt, just normal, and haven't had much added salt in the last couple of days.
I sit at a computer about a week or two a month and it swells really bad then.
What are the main reasons for swelling.
