Hello there,
I am dr.milan an infectious disease specialist answering your question.
I suggest you to ask weather the culture report has been done or not. As you have said its a one of the best hospital so they have surely done.
If infection is persist sometimes we need to remove that implant that happen in this case. Now you go for culture report of any discharge from that wound and also go for
blood culture by a reliable microbiology l;ab and by a qualified Microbiologist doctor.
Once you have cultured and if any organism is derived you need to follow just sensitivity pattern under guidance of your physician.
So, some organism need long term treatment for complete clearance. If it is not given for proper period they may come back and make you infected again and again.
So just go for culture & follow a good physician advise.
Hope i have given appropriate guidance to you.
if you have any query you can consult me anytime.
Give me star rating, helpful vote & thank you according to your satisfaction level.
Thanking you.
