Yes..I have citrobacter koseri in my sinuses causing me great discomfort, much pus. My sinuses are burning along with my mouth, throat and ears. My ENT gave me cipro but it did not work. My ENT is afraid of giving me IV atb because she is unfamiliar with this bacteria. All of my immune tests came back negative and the ENT seems to be more concerned with how I got this and not how to fix. I am getting more sick every day. I am in healthcare and am worried I can spread this. Should I get a second opinion so I may be treated before I get to sick?
