Hello, could you please advise me? My mom asked for advice on how to treat a very severe breast inflammation. She is a woman of advanced age and full-figured, she doesn't wear bras but constantly wears warm sweaters. She has been applying zinc ointment, Decongestant cream, Bepanthen, and even washing with iodine and green tea, but there's no improvement. It's very itchy and there's strong redness. Everything is complicated, she refuses to go to the hospital. What can I suggest? Is there any good cream or ointment?
