pain
"I have been taking Nucynta for about 1 1/2 years now for Fibromyalgia pain in my back. I started on the low dose of 50mg and that worked for a while but had to move up to 75mg. I think I may have to move up to the next mg dose again but that does not mean that the medication is not working. Over the years, my fibromyalgia has slowly gotten worse and I was not on any pain medicines for it because I did not know what was wrong with me. The only side effect I have experienced (besides the drowsiness for the first 2 weeks of taking the medicine) is being itchy. This is a medication that needs to be given the chance of at least 6 weeks before you decide that it isn't working."
