"i took it (2 a day) for a few weeks for a compression fracture and it helped not only that but the constant arthritis in the lower back. i also took it some years ago, knowing only the generic name and not associating it with &#039;vicodin&#039;, for shingles. nothing short of heroin can eliminate shingles pain, but this did a pretty good job without any sign of physical dependence. i will request a continuing prescription just for the arthritis."
