Pat, my mom had swollen, weeping legs and feet. They were discolored, almost purple with cracks. She has congestive heart failure (and has had it for years) and was retaining a lot of fluid. The fluid not only collected in her feet and legs, but began to collect around her heart and lungs and she was having difficulty breathing. Her cardiologist adjusted her diuretics and she's much better now. Her legs and feet are no longer swollen, the cracks have healed and the discoloration has lessened. I don't know if this is your mother's problem, but it might be.
