I have been feeling numbness, tingling, and burning in my feet. My middle toes on the left feel as if they are swollen on the underside, but do not appear so. Weird! Anyway, I am going to try taking chlorella (sp) which is supposed to detoxify the body of heavy metals including mercury. Do not take any fish oil or eat fish unless you are sure it is lab tested for mercury. The chlorella takes a couple months of regular use before you may notice feeling better and before it is working at its max. Always give the holistic approach sufficient time to do its job and then you can say for sure whether it works or not. When I start my treatment, I will not stop for at least 4 months or so and if it works, I will shout it from the highest tree. Anyone out there tried this? Thanks
