You can buy the ingredients of Metanx over the counter and leave the B6 out.
Methylcobalamin and methylfolate (Solgar) you can get yourself.
There is quite a bit of folate in Metanx, and you may not need the really high dose. Start at 800mcg/day.

2 of these a day ON AN EMPTY STOMACH....
I would ask that doctor for specific proof that B6 causes "pain".
B6 is a cofactor in serotonin manufacture, and that is often a treatment for chronic pain patients...to increase serotonin actions in the brain.
Doctors only know there were in the past a few reports on really high intake of B6...500mg a day for a long time to affect nerves negatively. Low B6 also causes neuropathies, probably far more often than any high reading.
