"i have been taking oxycodone 30 mg for about 4 years now.  i have chronic pain issues (arthritis, scoliosis, neuropathy, bulging disc, bone spurs and many other pain causing conditions).  i also have been diagnosed as having rectal cancer oct of 2014.  i have had only one bad side effect with this medicine and that is constipation. i now take miralax every day and i no longer have constipation.  this medicine does take away the pain.  i am glad i no longer take vicodin as it was wrecking my liver and kidneys because of the acetaminophenin."
