Well, back from bird watching in Suffolk and a bladder problem occurred whilst there. I am wondering if it sometimes happens that the bladder or urethra is disturbed by the sig procedure. My personal theory is that it is an E coli infection caused by the person who performed the sig. After removing the instrument he wiped me "back to front" as it were, thus propelling any germs from the bowel helpfully towards the urethra!!
I always practise strict wash hygiene post bm and have been cystitis free for years till now. Oh well - on with the bicarb and water and the trimethoprim. MSU in tomorrow for analysis.
I must have one of the most tolerant and forgiving husbands on the planet!!
