Husband Has New-onset Lower Extremity Redness, Swelling And Weeping In

Husband has new-onset lower extremity redness, swelling and weeping in one leg. We have been using antibiotic ointment and elevating the leg. He takes CHF and anti-hypertensive medications, as well as Eliquis, metoprolol and lisinopril. Wondering if use of vinegar would be beneficial.
