I Have MRSA In My Right Knee... 4-5 Days After

I have MRSA in my right knee... 4-5 days after initially seeing the urgent care doctor and taking Bactrim for those same 4-5 days i ended up needing the infection to be sliced open amd drained. While the doctor squueezed the pus out of the infected area out came a clear pus, a muscusey pus, and a strange white and stringy pus, or something also came out. The doctor at the urgent care didn't know eaxctly what it was. But guessed at it being coagulated white bllod cells. And also ask if myself or anyone in my family has ever had gout. The answer there is, no..

So my question to you is WHAT IS that stringy, white, chunky pus coming out with the normal pus???
