Cymbalta and other antidepressants in the "serotonin" affecting family have this effect.
Some posters on our PN board have found that Wellbutrin works on their PN pain well, and does not typically have this side effect.
It works on the dopamine system.
You might ask your doctor to switch you. There is really no trick to fixing this side effect that I have heard of yet.
Do you know if you had B12 measured? If so the numbers?
Lab ranges are very low for this test still and have been replaced by a new low of 400pg/ml. You might check out that "normal" and see if it is really "normal" ... it is very common to be quite low and doctors miss this result quite often.
