Hi I take oxymorphone 15 mg ER for chronic nerve pain in my neck. I take this 2 times per day, every 12 hours. I have been having withdrawal symptoms though. Anxious, cold sweats (I wake up soaking wet) body aches, some nights I wake up and can t move my legs and arms from pain, dripping nose, over active watery eyes, outrageous hot flashes where I actually feel like my body temp must be at least 100 degrees. Then again sweating, my face will be dripping wet even. Also having yawning issues, extreme and I mean extreme fatigue. I can sleep 3, 6,8, or even 12 hours and no matter what I wake exhausted and feel exhausted all the time. My doc has recently changed my dosage to 10 mg ER now 3 times per day. Thinking it might help and it hasn t. Still having the same issues. Any suggestions? I need help, with my pain I have little quality of life and now with all of these symptoms I feel like I have less than zero quality of life. I struggle to even leave my house.
