I just went thru this after my first knee surgery,I definitely would contact the surgeons office and tell them what you have explained here.they will probably call in an anti biotic fr you to get started on.this is what they did for me.the best type of anti B for this would be cipro.i was on this for the full ten days and then things were fine.except then I started leaking synovial fluid from the incision which of course required another surgery,but that infection was pretty much stopped dead in its tracks with the cipro,my biggest problem was that I have a very very bad GI reaction(horrid stomach burning for the full ten days?)but she also told me to take zantac about an hour before evry cipro dose and I amazingly had no problems at all,for the very first time.

I would do what the office told you and put nothing else on the incision as in some cases,for some reason,this can just exascerbate the problem.just keep it covered to catch any drainage,and prevent something else nasty from just comming in contact with an open wound on your skin.

but you DO need to get started on an anti B as soon as possible.the sooner the better or the infection will become much harder to treat if it should become a systemic issue.

hopefully things will be okay once this runs its course.this will just take a bit of time.please keep us posted on how things are going.FB
