Hoping that somebody is around at this time of night to talk me down, I'm on a night shift at work and feeling very paranoid about this almost constant UTI I seem to have had since May.
I dont want to give TMI but it may be relevant so I will tell you that it initially started when DH and I had sex in our hot tub 
The next morning I felt I was peeing razor blades so trotted off the the out of hours for a course of trimethoprim (3days)
This seemed to work but less than a month later, again after sex I woke up with a UTI so off to the OOH again for some nitrofurantoin this time, again clears it up for a few weeks and then again after a few drinks and sex I wake up with another UTI!
I had a longer course of trimethoprim for this one from my own GP.
I was symptom free until we went on holiday when it reoccured, I got a course of co amoxiclav this time which seemed to cure me.
A month later its back again, then back the next month which is where I am now, my GP sent a culture to the labs and its apparently an E coli infection, I am now prescribed cephalexin which doesnt appear to have entirely cured it and I'm 3 days in to a 7 day course.
I am being driven mad, scared to have sex with DH and petrified that I have bladder cancer (I suffer from health anxiety).
I have tried D mannose which takes the edge off the symptoms but they seem to return if I miss a dose so hardly curative. I still need regular antibiotics.
Theres no blood in my urine other tgan a trace when I have an infection but it is always strongly positive for leucocytes.
Has anybody ever suffered a constant UTI for six months? Did it ever go away, and if so how?
Any helpful advice would be very much appreciated. I am driving myself mad googling bladder cancer symptoms.
