My donor evaluation testing is on the 25th of this month, 12 days away from tomorrow, and I just found out I have a urinary tract infection. The nurse at the Quick Care clinic gave me a RX for Bactrim and when I told her about the upcoming tests she didn't seem too concerned. I came home and looked up Bactrim and potential side effects and now I'm scared to get the RX filled tomorrow. Should I call the transplant coordinator first? I've got to do something, this UTI is pretty uncomfortable. Any advice??
