Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that it is not a rare finding when chronic limbs' edema complicates with skin irritation and superimposed infection. Besides the advices given by dermatologist, I would recommend to promptly treat the predisposing substrate; that is edema (it leads to inadequate blood circulation to the surface tissues, predisposing to more readily skin inflammation). I would recommend adjusting CHF therapy; especially loop diuretics. At least an intravenous root of administration would be preferred, to decrease congestion as soon a possible, and an appropriate oral maintenance dose should follow. A comprehensive clinical evaluation; physical examination, coupled with cardiac ultrasound conclusions, liver and renal function tests, blood electrolytes, chest X-rays would better guide optimization of CHF therapy. You need to discuss with his cardiologist to review these data and make the best decision. Hope to have been helpful. Greetings!
