Increasing bladder infections

Patient: Am having multi bladder infections over years but now they are getting more frequent. Have blood and pus and tissue from repair (sling) once. No cancer tho the last one lasted 3 wks. I am worried about all different meds I am taking for them. Found some info for probiotics and herbal remedy marshmallow root but Dr. doesn’t know about them and am getting up about 5 times a night for bathroom. I am 76 yrs. old and getting really frustrated. Hope you can help.Thanks
