The reason I asked the above question is my PCP prescribed generic for Norco..because I have been having upper back pain ranging from the base of my neck down my spine to where a bra ends. When my PCP had Xrays done he found 2 fractured vertibre with no apparent reasoning why. That lead to a Bone Density Test. Which basicially said Osteopenia. Meanwhile I work in a elementary school Cafeteria and by the time I get off Im in agony. I can not quit work we need the income so I asked for something stronger so I could continue working that's when Tramadol came. I am also seeing a Pain doctor who gave me a Medial Nerve Block that lasted maybe 2 days and I have been in agony since. If the Norco is stronger why would he give me something weaker knowing I'm in alot of pain?
