I'm not sure why you would be going through this again. Algin helps the vast majority of people but I do find someone here and there who seem to have a bad reaction to it, but I don't know why.

About the pain in the back of the neck...

Some people seem to feel an electrical kind of pain while others seem to have muscle aches. My business partner had very tight neck muscles that we eventually found was caused by mercury-induced magnesium deficiency. She does much better with Magnesium supplements.

As far as the electrical sensations go, I just don't know. It's amazing how often I hear about electrical sensations in different parts of the body by those who are mercury toxic.

If you find out please let me know.

Thanks.
