"i had back surgery a year and a few months ago for a ruptured l5 that was causing severe pain in my lower back and down my leg. the surgery was not a success and am worse now than i was. tried injections having nerves catheterized, and physical therapy, none of which helped. my dose of norco&#039;s just kept getting higher and higher to where they couldn&#039;t give me anymore and be able to perform my job. my doctor put me on the butrans patches and the relief i get is absolutely amazing. very seldom do i have to take the norco&#039;s. i started on the 10 mg and now am at 20mg. like others my only complaint is about day 5 or 6 they start wearing off then takes a day for new patch to start to work. overall they have made my life more comfortable than it has been."
