Sorry for the delay in responding again.
( I actually see patients in real life, and was busy in the hospital and office all day.)
As can be seen in my profile I am based in Chicago, but the JA policy is not to provide personal contact information offline. This is to protect everyone involved.
I am quite positive you should be able to find many very well qualified and excellent clinical infectious diseases physicians in most large hospitals- If you are not satisfied by the opinion you received from the one you already saw- you absolutely SHOULD seek another opinion from another ID doctor offline.
My concern, as noted is if there is indeed residual infection deep in your wound- I cannot be certain without more investigations and a proper assessment, but that would be the concern that needs to be addressed.
Betadine does lower bacterial counts before surgery and is commonly used- but having said that, Staph. epi remains the commonest bacteria that infects foreign bodies after surgery- So clearly effectiveness is far from 100%.
Good luck and let me know how it goes.
Always ask if you need clarification/more information.
POSITIVE feedback & a BONUS are warmly appreciated.
