ach, you poor thing Divis! I feel for you. I had a kidney stone while travelling round Mexico - I couldn't walk or breathe for the pain and ended up peeing blood too, so I sympathise, though yours sounds a lot worse. Hadn't heard the trick with the lemon juice but I'll be trying it. Touch wood, I haven't had one since, though I've been through plenty of urology checks (ultrasounds, dye tests, x-rays) as apparently I piss too much blood for someone of my tender age. I would've thought that pissing blood at any age was pretty too much!
