breakthrough pain
"I have used Fentora for breakthrough pain due to RSD which is a nerve disorder.  The medication when I can take it makes a huge difference in my daily routine.  Unfortunately the last 2 years my current insurance will not pay for it so my family has been paying for it.  Initially we paid $4000.00/month which quickly became impossible.  I am currently taking 1/4 of my daily dose I should be on.  Needless to say my daily routine now causes me to spend a lot of time in bed, pain and nonproductive."
