I think it's possible that things go the reverse. I had fibro type symptoms before the pn (I dont' anymore) and myofascial release, which ended the fibro, helped the pn.

My speculation on this is that trigger points are gummy points that cause tightness and pulling of connective tissue, and by doing this around vessels and nerves can decrease the nourishment of nerves. Anyway, deep bodywork helped both for me.
