--though it might depend on the type of anemia.

But, of course, we've all had doctors who don't have a clue about vitamin or mineral contributions to our conditions--or to helping them.

As far as your "jump start" theory--anything is possible. I suspect, though, that those of us with some nerve damage are simply more prone to compressive nerve effects than "normal" people. Our nerves may not be symptomatic all the time, but since they are comprimised in some way, any "torque" or "pressure" on them--mechanical, or from the swelling of a bruise, or whatever--can get them to express symptoms "sooner" (through the application of a smaller amount of pressure) than it would take for someone without such comprimise.

This is actually very common in diabetics, BTW--they are more prone to carpal and tarsal tunnel, and to meralgia parasthetica, compressive syndromes all, than are those in the "control population". Many of us with "idiopathic" syndromes report similar things. In fact,in my case it has been speculated that my compromise may be causing me to feel my right side cervical radicular symptoms with less pressure/less narrowing of the foraminal space than it would take for someone who has never had a nerve issue.
