"male, mid 30&#039;s, 2 herniated lumbar discs, 3 pinched nerves, bone spur, stenosis.. i have been on pain meds for the last 10 years, and opana is by far the most effective paid med i&#039;ve ever tried and believe me i&#039;ve been on everything.. most recently i was on oxycontin 20mg 1x a day and oxycodone ir 20mg 5x a day.. the problem with oxycodone is that it has a very low half life of 3-4 hours and is very addictive because of the short duration of action you find yourself &quot;chasing the pain&quot;.. i suggested opana to my pm doctor as i heard good things about it, best pain relief i&#039;ve had in years! i take opana er 40mg 2x a day and opana ir 10mg 2x a day prn for breakthrough pain.. this med is a wonder drug for those in 24/7 chronic pain!"
