Hi I ve been suffering with UTI s for nearly 20 years but recently they be been more frequent and I ve noticed they pretty much always come on after sex. They last for 2-3 weeks and I suffer with burning as high up as cervix, whether I wee or not. I use everything from pessaries to cream to sodium citrate, gallons of water and cranberry juice and nothing works. I don t have itching, spots or weird discharge normally until this time when I had new flesh like discharge. Can you advise please?
