I don’t get face pain, but I do get that tingly stuff in face, arms, hands, legs. Nasty. Its pretty common for mercury toxic people. Certain foods affect it and make it worse with me…large quantities of pumpkin seeds and coconut oil bring it on real bad. Sitting in front of my PC brings it on bad too. Parasite cleansing makes it go away for a couple of months, but then it slowly comes back again, so I parasite cleanse again and it goes away.

Vit B12 intially calmed things down for me, but not not anymore. You could try that.
