I have CRPS or RSD for 6 1/2 years and have been on 75mcg fentanyl for 6years. I recently tapered off fentanyl due to losing weight and it wasn't absorbing correctly so I was having bad side effects. I've been completely off for 3 days and can not stand the pain in my bones at night(completely different from RSD pain). How long will this last? I am taking Norco 10/325 (at least 10/day) also doctor prescribed Zanaflex and Clonidine to help with withdrawl, but this bone pain is so bad and my body twitches. It is worst at night. Any suggestions would be greatly appreciated. I need to sleep, I have 4 kids and am exhausted. If I knew everyday would be like this, I don't think I'd have strength to live. RSD pain is awful but this is like scratching nails down chalkboard but feeling deep in bones. Any suggestions appreciated. I've never posted on a board before but can't sleep, so why not. I'm a very strongwilled person and can handle most things. I've been on a ton of medications over years and even tried a ketamine infusion of 200mg/hr a few months ago(that was awful and didn't work), but never have I felt like this. I think part exhaustion and mostly crazy weird pain without being able to control twitches. Thanks for any nice advice.
