chronic pain
"I used Oxycontin to deal with leg and terrible back pain.  I was taking Vicodin, and if I didn't get ahead of my pain, I ended up using as many as 8 a day.  All of the acetaminophen was damaging my liver.  When I switched insurance companies, I had a regular doctor and a new pain management doctor, who told me that the Oxycontin was a better medicine for chronic pain because it does not have the ups and downs that Vicodin has, because Vicodin only lasts about 4 hours.  I used the medicine for many years.  I now use the Fentanyl patch with great results!"
