I have extremely similar symptoms to
you. I had a bad UTI
for a guy and while several tries on antibiotics
helped, the symptoms have never truly gone and I relapse into them from time to time.
In my case I go into a detox mode for a few weeks before visiting the doctors as they are convinced I have an std or something. Either way, I find the following helps me: cranberry justice, flax seed oil, plenty of fresh fruit and veg, lots of water.
