I have been on Cymbalta for 7 years and I am suffering from the following symptoms, pain in my upper stomach, ulcers, dark urine, difficulty starting urine, fast heart rate, memory problems, blood in stool, protis, rash with puss blisters, skin peeling, and glucoma. This has all began in the last two years, I have never questioned any Dr. about the possibility of this being related to Cymbalta, but today reading up on this medication and its side effects I can not help but question. I was diagnosed with Glucoma just yesterday.
