"i&#039;ve been using this patch for 2 and a half months. it helps my pain a little but i feel that this stuff is a joke. i started at the 5mcg dose and am now on the 15mcg dose. my pain management doctor refuses to try something else. i stay nauseated and constipated. i get rash and blistering at the patch sites as well. it&#039;s all the bad side effects of pain medicine without the benefit of helping pain. the only good part is that it weakens considerably after 2-3 days so i get to eat some. it&#039;s worthless as a pain reliever for me."
