Should they biopsy?
Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. I suspect MRSA in you. It is a type of Staphylococcus aureus infection which is resistant to multiple antibiotics. I advise you to do sensitivity testing of the staphylococcus bacteria. If it is found to be MRSA than it requires a strong antibiotic treatment. There is no need to do biopsy. And you also cure completely this way. Please avoid share of household with other family members as it can spread to other members also. Please maintain cleanliness and hygiene as it is equally important in treating infection as the antibiotics do. I will be happy to answer your further concern on bit.ly/ Chat Doctor. Thank you, ChatDoctorInfectious diseases specialist, ChatDoctor.
