I had a UTI about 5 days ago, but the symptoms got better. However, starting yesterday, I felt it again but not as severe. I ve been drinking a lot of water (since 5 days ago), so RIGHT NOW by urine doesn t really hurt. However, I have been getting chills and have a fever. I don t have much money, so I m wondering if I can cure this now, or if it is very serious. I also think I have slight lower back pain (I realize this might mean I have kidney infection)- but can I make these go away by drinking a lot of water and cranberry juice? I don t have much money so I don t want to go to the doctor if I don t have to. The fever is what scares me the most.
