"i have been on cymbalta for about 3 months. it helped with depression but made me tired most of the time. a week ago, my doctor increased my dosage from 60mg to 90mg and i developed a uti and have very intense middle back pain. uti has been cured but back pain persists. i just read on a few different threads that cymbalta caused others to develop bladder infections and back pain, two things i never had prior to taking this drug. this drug also causes me to sweat profusely to the point i feel like i am about to drown in my own sweat. i was never a sweater. i am going to discontinue this drug."
