dercum's disease
"I started using fentanyl for Dercums disease over 4 years ago. I started on  25 mcg. and worked great until my body demanded more or became used to the medicine. I went to the 50 than to the 100 mcg every 48 hours. I felt normal again from the pain of this horrendous disease to a point! No one really understand how extremely painful this disease is! I just had a pain pump installed in October just because its much safer for long term use, and I will say what a difference if it wasn't for this medicine I'll be as honest as possible I would have taken my own life! It's that bad, I just wish more doctors would research this and understand, not make people think its all in their head. which they do!"
