Sunday evening I got a twinge of pain in my left flank. It didn't get any better, so I treated it to a nice hot Lush bath, on the grounds that it was probably a pulled muscle. That seemed to help, so I went to bed, resolving to treat my body more gently for a day or two.
By 5 a.m. I'd woken Jus up with my whimpering and I could barely speak coherently from the pain. Which, I'll remind people, is pain that's got through 50mcg/hr of fentanyl and 80mg of morphine sulphate.
I just about managed to keep it below the screaming point by getting Jus to supply me with hot water bottles as hot as I could bear, and then I decided that this probably was something fairly serious, and asked him to phone NHS Direct. All the questions being answered, their autodiagnosis package suggested that I had a urinary tract infection, and that I should go to the doctor ASAP with a urine sample.
I finally got to see a doctor at 10 a.m. or thereabouts. He took one look at my sample and said "Nasty!" Pus, blood, the works. Hence I'm now on 1500mg of cephalexin/day (mercifully, even though I'm allergic to penicillins, I'm OK with cephalosporins) and am waiting for a urologist appointment.
It seems to be doing good. Apart from a few nasty twinges on Monday and Tuesday, the pain's all but gone. Much relief.
