Hi, I have been living with Ulcerative Colitis for the past 10 years and was swapped to Mesalazine 3 years ago. In the past 13 months I have experienced visible Hematuria with pain in my lower abdomen. I have had all the investigations done from a urology standpoint with no clear answers.
However, In the last 3 days I have had left flank pain with 8/10 pain which comes and goes. The ED Doctor seems to think I have Interstitial Nephritis which is one of the side affects of taking Mesalazine (which I was unaware of)
Has anyone with UC taking Mesalazine experienced the same symptoms?
