Extreme pain in hands

For several months, I wake up in the middle of the night with the feeling that my hands are on fire! Upon waking in the morning, there is numbness and tingling. About 2 weeks ago, I woke up with the feeling that my left hand was broken with deep pain in the bones and joints of my fingers and into the palm of my hand. One of my doctors said I have developed "trigger finger" due to carpal tunnel, and he has referred me to a hand specialist. One of my other doctors recently ordered some lab work for me (for something else), and discovered I have extremely low vitamin B levels, and has put me on a regimen of monthly shots and oral supplements. I am now confused and extremely concerned that my hands are going to permanently feel like this. There is no improvement so far. My left hand still feels "broken" and the right one continues to go through periods of tingling and numbness. Could Vitamin B6 &12 help reverse this pain? Could there be permanent damage that will require surgery? I can't continue enduring the pain and have no idea what to do next.
