Pain
"This medication works better on certain medical conditions, particularly spine pain of any kind, and moderate acute joint pain, and acute muscle pains. It is an opioid, though working differently from the other opiates,  and will act as one - in that you may get withdrawal symptoms if using it for a long time. Likewise if you start using it at higher doses (like 2 tabs) you will experience the nausea that comes with opiate use. Better to start it at a low dose of half to 1 whole pill, and work up if needed. Only take this pill at the minimum dose you require for the least amount of time necessary, unless your doctor tells you otherwise."
