back pain
"Issues at L5/S1, muscle spasms and two injuries. Been taking Norco 10/325 for two years. Great relief for lower back. Within an hour I feel 100% better. Depending on severity I take 1 to 3 a day. No adverse effects. I am not left in a stupor and can function in daily life.  Another important factor is the amount of Tylenol. Very minimal and easy on your liver."
