"severe lower back pain, sicatica etc.  pain management doctor gave me injections in spine which made it worse. i finally found a great doctor that went thru everything from lowest non narcotic to the fentynal patches. oxycodone has given me a life back, i take two 15 mg. tablets every 8 hours. they take 45 mins. to take effect for me. i can walk, do some things around house not just lay in bed.."
