It is hard to tell and I know why you ask if it disguises symptoms, because I felt the same.

I think the more important question is, has Cymbalta improved the quality of your life? If it has it could be a useful medication to take on a temporary basis.

Many of the physiological symptoms are exacerbated by psychological symptoms of PCS. Medication can break this cycle.

In my case it has greatly improved the quality of my life, and things are pretty much back to normal. The next step is to withdraw from it in the next few weeks under the advice of my doctor. I suppose only then will I know if I am healed.
