Hello, Welcome to health care magic. You seem to be having recurrent furunculosis. I assumed that they have given antibiotics based on your pus culture and sensitivity reports. But inspire of that, the bacteria can sometimes form a colony in our skin and cause recurrent infections. You could ask your dermatologist to check for carrier status by taking swabs from your nostril area, skin around the umbilicus and around the anal orifice. These are the sites where bacteria form colonies. You could use topical mupirocin creams in those areas for 5 days in a month to eradicate the colonies. Use an antibacterial soap.consume vitamin C rich foods and take multivitamin tablets . Hope this helped. Take care.
