My pain management doctor just offered me Belbuca for pain. She said it works for both nerve pain and "regular" pain. Not sure if regular pain is the correct wording there but hope it makes sense. She gave me a big packet of info. on it. Has anyone heard of it before and more importantly, has anyone tried it? The info. (side affects) seems kind of scary but I think I might try it out. It's a little square that you put on the inside of your cheek and it dissolves offering 'round the clock pain relief. Can you imagine??? I had Fentanyl patches for 13 years without any real troubles. I would get a little sick if I got too hot so I had to be careful about being outside when it was hot, in the shower, etc. Other than that, it was a great pain reliever. When they had me get rid of it I didn't have any bad side affects at all. I've never heard of Belbuca before but I'm curious to find out if it offers similar pain control. It might be something to ask your doctors about.
