chronic pain
"Similar to other reviews, Belbuca did not relieve my chronic cervical pain.  My pain management physician started me on 150mcg January 2016, and within 90 days, moved me to 300mcg. I received minimal pain relief from this medication, (about 2 hours) and the packet can be difficult to work with.  Regardless of following the directions, I received inconsistent results when it came to how the medication is designed to dissolve. At the end of the day I no choice but to move back to my original pain medication."
