I can't tell you anything about Kratom....but I can tell you that if you have been taking Tramadol then you have been on an opioid pain medication all this time. So maybe there is less for family to worry about with you going back on Nucynta

. I mistakenly thought you had nothing for pain besides the kratom.
Perhaps the Nucynta will not affect you as badly as before since you are taking the XR version. You were on regular version before right? I would give it some time to work. If your pain has been really high it may take a few days to get you out of flare. The XR of drugs work differently and may not pack as much immediate punch.
I am glad to read that you have a counselor. It is good to have support for your burdens. Would your wife consider going with you for even just a session or two to work through the med issue? Or maybe go to your next doctor's appointment? Perhaps that might shift things a bit...
