"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."
