"i was hurt on the job back in 2006.had a disc removed and fusion of l4 and l5 in my lower back.i  have suffered for years with chronic back and leg pain because of this injury.i was on 80 mg&#039;s of percocet  a day for 2 years and was taken off of it,cold turkey as they say,by my dr.

after 5 days of terrible withdrawl&#039;s,my dr. put me on opana er 10 mg tab&#039;s,twice a day.they helped me with my withdrawl symptoms but didn&#039;t do much for my pain.

my dr. agreed to up my dosage to 30 mg&#039;s,twice per day.

wow!!!! what a difference these 30 mg pills make.pain is about a 1 on a scale of 1 to 10 and i can finally sleep again.

it is known that only 10 percent of your dose is actually absorbed by the body and the rest is eliminated when taken orally."
