"i have been in constant pain for 17years (since i was 12) rsd, chronic migraine, fibromyalgia, myofacial pain syndrome, sjogrens, and several other things. tried everything to manage the pain and gain some of my life back. the only thing i found that helps is nucynta. i have been on it for about 4 years, (1) 100mg tablet every 4 hours. it&#039;s a love/hate relationship. it&#039;s the only thing that helps my pain, but i hate waking up every morning going through withdrawal bc i&#039;ve been on it so long. i tried the er but it wasn&#039;t as effective. i know it&#039;s not good to be on it for so long but i&#039;m at a loss for any other options to try, and it really does help me be more functional than i was without it. besides the withdrawal i have not had side effects"
