Hi, My Mother Is 89. She Is On Lasix And

Hi, my mother is 89. She is on lasix and hypertension medication. Her legs swell and drain out of sores that form on her lower legs. They've upped her medications and it helped somewhat but I wonder if there's more we can do. She has trouble walking now, too and the draining, swelling and discoloration don't get any better. Thanks, Rex Kramer
