Does Carisparidol Help In Treating The Pain And Numbness In Arms?

I was diagnosed with A-fib in January - subsequently I also have bone spurs in my neck that are affecting the use of my right arm and numb finger tips, just started affecting my entire left arm (I m a lefty) with pain. Being treated with fentanyl patch 25mcg for pain (barely helps) would if be helpful (pain wise) to ask for soma/carisparidol?
