I have yet another urinary infection needing me to be on Fluoroquinolone for 3 weeks. I have already started the treatment yesterday but I am quite afraid of the possible adverse effects. I have told me family doctor about my fear but it dismisses it saying that FQ adverse reaction are more acute and appear during treatment not after (but a lot of website say the contrary)I have been on FQ 3 times before, and I still consider that it could be the cause of my BFS. I know some on the board also had been on FQ and suspect it to cause their BFS. For those in this case, did you went again on FQ after your BFS started ? If yes, did you had any adverse reaction ?Thanks,Christophe
