My father started getting swollen feet withing the last week. Today after coming home from work had to peel his jeans off with major swelling in the calves too. One is bigger than the other. They are very red with blotches. He said his calves are burning. They are warm to the touch. He wouldn t go to the doctor after the swollen feet & we are trying to talk him in to going in the morning. Could this be edema or could it be more serious like a possible blood clot?
