Mom is 92 yrs old and has congestive heart failure (CHF), afib and now recurrent cellulitis in her left lower leg. She has edema in the leg and her skin splits and gets infected. This is her third bout in 6 months. She is on a blood thinner, Lasix, metoprolol, levoxyl, and she has a pace maker. The doctor treats her each time with an antibiotic and a topical cream. Anything else we can do to prevent this? She is a clean person, and it seems this pops up out of the blue every 3 months or so now.
