I just completed the survey.

I've been taking Nucynta for 3 months. I had a ruptured disc, repaired via microdiscectomy. A fragment of the blown disc was compressing my sciatic nerve and I could not use my right leg. The sciatic pain was gone when I woke from surgery. However, several months afterwards I began developing horrible lower back pain. I also have RA, and the pain from that is mainly in my hands and feet.
I was taking 5x10/325 norco per day with not much relief anymore. My rheumatologist sent me off to a pain management specialist because she couldn't/wouldn't prescribe anything stronger.
Pain management guy thought Nucynta would work well for me. Dual mode of action, tolerance builds slowly if at all, etc. I was elated when my insurance actually paid for it.
The first dose (50mg) didn't do anything for me so I popped another one an hour later (this was OK'ed by the doc). Even with two doses onboard I wasn't getting much relief. Then, a few hours after taking those initial two tablets, my pain started melting away! I was initially prescribed 4x50mg/day, but for me they wear off after 3 to 4 hours. My doc told me to wait a few days in between dose adjustments, up to 6x50mg/day. That was the sweet spot!
My husband and co-workers noticed positive changes the next day. I wasn't walking like an old lady (direct quote from husband) and I had more energy, stamina and strength at work. I work at a very tiny brewery, where I do the brewing and QC work. Lots of heavy lifting, long long days, and standing on a hard concrete floor all day long. I used to take frequent breaks in my zero gravity reclining lawn chair while at work due to pain (ZOMG I love that chair!). But, after starting on Nucynta, I was back to my pre-surgery capabilities! Lifting 50lb sacks of grain, doing the entire brew by myself with no assistant, and no more need of my ghetto lazyboy lawnchair. I no longer wake up in extreme pain. I can enjoy sex again without feeling like my back is about to break. I've lost 5 pounds (went from 140 to 135), which I assume is due to my increased physical activity level.
In short,
I absolutely LOVE this drug. It's given me my life back! For me, it works far better than the Norco I was taking.
