Cymbalta and chronic pain

I' m a 49 year old female. I took this nasty drug for just two days to try to control chronic pain of fibromyalgia. The first day I was ok. The second day I was on my way to work when I felt a severe attack of diarrhea. I didn't make it to work. I pulled into a parking lot and before I could get to a bathroom I lost complete control of my sphincter muscle and messed all over myself. In the meantime I was projectile vomiting. My heart was racing and I felt like I was going to die. The only thing that kept me from calling 911 on my cell phone was the embarrassment of having soiled myself! It was one of the most frightening and horrible experiences of my life!
