I’ve known I had pseudomonas in my sinuses for 13 years. I was on IV antibiotics then for 3 months but they were improperly given I later learned from Infectious Disease at our hospital. It remains dormant until triggered. I knew 2 years ago it was active but couldn’t get a culture to show it. It has a neon biofilm around it. If you are getting drainage with an almost clear sticky neon color, that’s biofilm. I was again diagnosed about 3 months ago. I took Cipro for 6 weeks (recommended by the lab) and the Pseudomonas GREW. Then I was but on IVs of Impenum and that is 3 times daily for 5 weeks and my drainage is still green. I go to Infectious Disease tomorrow. I am not playing around with this any longer. It can be fatal. If it’s in your bone you need to go somewhere like Cleveland Clinic. Mine has shown up on two MRIs over the past 3 years. I have lost all my teeth but 4 with the explanation it was dry mouth! Let me know anything you know. My research said only 13% of sinus infections are this bacteria.
