I've gone from being ok this morning to having an horrendous UTI in the afternoon amazing how quick it gets you! Got some anti-biotics & drinking plenty, feeling sorry for myself on settee, if you've ever had one you'll know how I feel!!
It tastes disgusting but I find that sipping a glass of water with a good pinch of bicarb in it helps to sooth the bladder. have it alongside whatever else you are drinking.
I had exactly the same thing just over a week ago. Antibiotics made everything taste awful, but I feel fine now. Hang on in there, you will get better!
