I am now 5 days post-op. Everything has been going as expected, from what OS, PA and everyone here at Bonesmart said to expect... with the exception of blood now showing up in my urine. First time ever for me, never had a UTI before, so this is a bit alarming. I called the OS' clinic today (weekend) and one of the OS partners did call me back and said I should see my GP on Monday if it persists through weekend. I have noticed it twice already. If this was caused by the catheter insertion, or removal, it seems the blood would have shown up earlier. And I don't have any pain associated with it. Could be the Celebrex or cephalexin? Anyone else out there with past experience or knowledge?
