"i am 47, disabled by the government. i have chronic pain for over 20 years.  i have had my right knee operated on 9 times.  a knee replacement and a knee revision. i&#039;ve had my back fused at l4 &amp; l5 (and need more fusing).
with working in the pharmacy field for over 30 years, i have used every pain medication that has come out.  i do not believe i am getting the relief i should be with opana er. i take 20mg twice a day plus percocet 7.5mg/325mg three times a day as needed.  
the pain is unbearable.  after 1 hour of taking the medication i still feel like i haven&#039;t taken anything. the percocet&#039;s help some, but i can&#039;t take them every 4 hours. 
i just want some relief and this drug doesn&#039;t give total relief."
