Medicine side effects are a funny thing (but we are not laughing.) The reason why the list in fine print about "possible side effects" is so long, is that someone, somewhere, sometime, had that happen to them. It may not be common, but there it is.

I have a side effect with the Humira it am taking for Rheumatoid Arthritis. When it first happened, I actually went to the ER. No one there could point to the Humira because it was not a "listed side effect." Same thing with my PCP and with my Rheumatologist. She contacted the manufacturer, and they had not heard of it, either. After it happened several times, to where there is a definite cause-and-effect, it has become clear that it is the Humira - along with everything else I am taking and all of my other conditions.

Someday, this side effect will probably be added to the fine-print list.

You may indeed have this because of the Cymbalta, even if it is not common. Be sure to report it to the doctor. This is how drug companies find out about things that need to be improved.
