I hope that they get you on antibiotics quickly enough to get ahead of it this time. Some people have a hard time getting rid of an infection. I am that way with strep infections, whether on the skin or on any part of my body. My bacterial cyst was even strep. I have so much that if my immune system gets the least bit low, it just multiplies like rabbits.

I hope they can get you on immunotherapy to help your immune system build back. Is it possible that after the wound vac came out that it didn't get put back well enough and it has built up? I hope it is something that is easily fixed.
