"i have been in pain management for 12 years and have been placed on about anything i&#039;ve ever heard of.  nucynta 100 mg 4 x daily does a really good job of relieving my pain from herniated discs. i&#039;ve mainly been on oxycodone 10mg to 30mg roxicodone and the nucynta works better than either of those for me.  it may be due to the amount of time i&#039;ve been on oxy as to why i can&#039;t feel it helping anymore.  been on nucynta for about 7 months now and its expensive and the worst side effect for me is drowsiness and having difficulty concentrating. i am in recovery now after c5/c6 replaced with titanium screws and a synthetic spacer so i&#039;ve been on a dilauded pump 6mg per 4 hours, 20mg roxi, 100mg nucynta, 700mg soma and still hurt."
