@RinTinTin It’s uncanny the way our bodies go into mini-revotl just before surgery! I had a pesky issue last weekend, too , before my surgery on Tuesday, but was able to speak to an on-call nurse and on-call doctor who gave me direction and calmed my worries. Like you , the pre-op nurse call asked me to stop all supplements two week before surgery, so I would not have felt free to add Vitamin C without their blessing. Interestingly, they also told me to cut garlic and ginger, because they have anticoagulant properties.
One other thing I was told to do - and wish I had started sooner - is hydrate, 64 ounces minimum, and as much as 80. I think it had a positive influence on my surgery.
As for the Hibiclens and the mucipricin, different surgeons appear to give different directions for their use. Sometimes those directions vary depending on the outcome of a MRSA/Staph screening. So again, it sounds like you’ll need either your doctor’s advice or the hospital’s advice to get this sorted.
My primary care doctor is the one who ordered a UTI culture to rule out a UTI infection prior to surgery, so that may be another avenue you can try to get clarity about your current status prior to the 10th. I would prioritize this, if you decide to seek a culture, as my results took a couple days to come back.
My last-minute “hitches in the get along” were frustrating and worrisome, so I sympathize. What worked best for me to resolve them was proactive communication with both my surgeon and my PCP, I wish you all the best, sorting this out, and feel confident that a short delay would be in your best interest, if your doctor decides it is warranted.
