"after a my injury turned from acute to chronic my dr. prescribed 10mcg patch. i was very skeptical since a patch seems very non-traditional but i gotta say it worked terrific. you put the patch on once a week and forget about pain/pills till the next week. so effective and convenient that multiple times i have forgotten to change it after a week. only downside is no hot tub/baths and no direct sunbathing, a bummer when you live on the ca coast! also no tolerance issues, was on same dose with same results for 2years."
