I was having the same problem a few years ago. After finding the right doctor who tested for more than just urinary infection, I was diagnosed with Interstitial Cystitis (IC). IC mimics a uti. And cranberry juice actually makes it worse. It is not an infection, it is a disease. There are treatments that can help with the symptoms. My suggestion to you would be to find an ObGyn who is familiar with Interstitial Cystitis and can do proper testing. If this is what you have, and it sounds like it is, then getting the proper treatment will help you feel a million times better. Hope this helps and you feel better soon.
