back pain
"I had a traumatic injury to my neck and shoulders about 7 years ago and didn't have proper treatment to repair the injury, so now I have constant moderate-to-severe pain in my neck/shoulder/back. Norcos really help a lot, but, as others have said, they don't last very long. I have to take 1.5-2 10/325mg tablets every 4 hours (at the most). 

WORST SIDE EFFECT: Constipation. By far. Since my back hurts all the time, the thought of going and playing sports is intimidating to say the least, so I don't exercise nearly as much as I should (I've gained 35 pounds since the accident and I'm 28 now). 

Overall this is a great medicine and one I would recommend."
