I've had blood in my stool, about once a week for the last 3 weeks. about 3 weeks ago, I had an episode of lightheadedness, and my doc told me to stop my meds (Imuran) until we figured out what's going on. Anyway, I eventually went back on the Imuran, but now off again bc I had a cyst removed from my skin, and wanted to make sure I was at full healing (and infection fighting) capacity. Could there be a correlation with not taking Imuran and blood in stool? Is this something I should be concerned about?? Thanks.
