I was on 30 mg Cymbalta for a week, now 6th day on 60 mg. I take in the am. I am male over 50. I began having these side effects on 30 mg and they have not abated: testicular and groin pain, worse at night; impossible to complete sex (not merely difficulty ); indeed, libido nearly non-existent, whereas healthy prior to Cymbalta. My question is not so much is Cymbalta the cause (it obviously is), but do these kinds of side effects last. No affect yet on my depression. Thank you.
