"i had a good experience overall with the butrans 15mg patches. suffered from a bad car wreck leaving me with severe occipital nerve pain, migraines, bulging disc in my neck and back. damage to l5, s1 in a fall and fibromyalgia. i tried so many meds was a ginea pig for trial and error. tried every pain med that was available and found i was allergic to all but two. after 10 plus years of being in pain i was finally able to get out of bed in the morning and sleep through the night. i could function without the drowsiness or loopy feeling pills left behind. i would recommend this to anyone in cronic pain not part time pain. the only side effects i encountered were 2 years later and are ichy, redness and blistering like rash at application site"
