I had a hysterectomy in Oct. starting in Jan . after several infection I now have e coli that I think has colonized in the bladder . It is one infection after the other. What to do? has anyone had this happen and what did yo do. I use D-mannose that has been a life saver ,but this time not keeping up with it well. I have had a cat scan, ultrasound, and the camera up the bladder . all ok . some days it feels very vaginal. Help Deanna Bain
