Oxymorphone
"In addition to Complex Regional Pain Syndrome I suffer from constant pain in my hip, femur and knee, L-4,5 disk herniations, spinal stenosis, spondylosis to start. I was thrown from a car as a passenger without seatbealts fracturing my hip, femur and my right foot pointed South. My experience taking Oxymorphone is an excellent one.  I recommend it to anyone seriously looking for pain relief. I take 30 mg Oxymorphone ER X 2, Ketamine Hcl(compounded for $125 a month) 10 mg X 3 and Oxycodone 30 mg X 4 for Bt pain. Oxymorphone is the best ER opioid for 9-10 hour relief I have taken. Tried them all. If looking for pain relief, Oxymorphone is the best by a mile, hydromorphone is a distant second."
