Stomach pain with a UTI can be a kidney infection. I would see a doctor. Antibiotics are horrible, but it is very hard to cure these things naturally, especially when they are severe or chronic. The most helpful thing for me has been D-Mannosse which I take in large amounts if I am having sex. Good luck!
I think you have to sleep on hard bed
You have to keep your body posture correct
You have to pour one teaspoon of Olive-Oil in to Navel [belly button]
I think you are suffering from this disease due to use of Antibiotics
You have to do exercise at least 5 days in a week for few minutes or more times
