"i was prescribed nucynta 100mg 4x day after years of being on hydrocodone, tramadol as well as oxycodone for back pain from 3 previous disc fusion surgeries. i have to say that nucynta did relieve my pain but for only maybe 1 1/2 hours at the most. the side effects are horrible, head ache, stomach discomfort, &quot;trippy&quot; feeling, just to name a few. i would also like to add that i was not in withdrawal from opiates when i took this medication, even though i was having mild withdrawals from the years of tramadol use and nucynta did help me with the withdrawal symptoms, somewhat. even though i do not want to continue opiate usage any longer nucynta is not the solution for my pain.
