This btw,

-lower back hurts and is weak


is a sure sign of mercury/heavy metal accumulation in your gut. Try a professional internal cleanse (colonic) if you can, should start to help take care of that right away. It'll settle from your gut into your behind and lower extremities if you do nothing about it, and then you will really be hurting. get it out of your gut while you can before it moves elsewhere.

A colonic (or two) will also help get rid of mycotoxins from parasite die off remaining your gut from the parasite cleanse.
