Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Yes, it is a infection at the surgical site. I advice you should be tested for Grams staining, culture and sensitivity from the pus discharge. Once the report received we came to know which organism is probably infected to you. Whether it so MRSA, MSSA etc. Accordingly you also got sensitivity report stating which antibiotic to use and which not. This infection should be given good local hygiene this can be maintained by local dressing and cleaning. Dettol and betadine can be used for it. Polysporin application at the end helps combat bacteria locally. Avoid further injury to the infected site. Please take care as to avoid any pressure over the infected site by muscular action. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
