My mother has a painful pimple/acne/boil at the tip of her right nipple. She is not able to bear the pain every time she moves. She has bandaged it after applying ointment similar to soframycin. However, 2 days and she is still struggling. Could it be breast cancer? She already has achieved menopause couple of years back so not possible to be pregnant. She is 60 years. We're scared to take her to a hospital because of corona. She has high diabetes, blood pressure and thyroid issues so want to avoid a hospital visit for fear of her contracting the virus. Please help.
