Butrans
"I have moderate RA with sacrum fractures due to my low back fusion and hardware.  I have cervical fusions as well with scar tissue and pain.  I was taken off my current medication for pain (been on for 6 years) and was put on the Butrans patch 20mcg/hour.  I became very ill, extreme migraines, stomach pain, fatigue to the point I could barely concentrate on anything.  I literally felt like I had the flu.  After a 2 week period on the patch it did very little to control my pain, and made it difficult to be active during the day.  I couldn't take this medication after the two week period.  I do not recommend this medication for people who have moderate to severe chronic pain."
