Hi, over the course of the last year, and as this seems to be progressing, I have had all the too familiar symptoms. But for the last 2 days, my left flank feels really tight and sore. I fasted today to try to bring it down, but just seems to be getting worse. Funny though, my knees feel great today, after about 30 hours of no food. It's just this side that's disturbing me. Anyone else out there have bad flank pain? Guess I need to hear if I'm the only one on this island. Thank you , God Bless
