Hi ! Just hoping someone sees this and has some sort of idea as to what I am talking about. I was diagnosed with atypical HUS June 2015. Since then my kidneys have been improving but I have INTENSE left side pain. It is right below my left kidney. After ct scans, getting my appendix removed and ultra sounds. No one is finding a reason for my pain. I am so frustrated. I am learning what I can about AHUS but does anyone have chronic pain with this disease?
