Hi,
No, I don't think your symptoms are related to sodium. Many of them are related to iodine. Also, get on a really good diet. The losing feeling in your feet is probably neuropathy. Changing to a vegan vegetarian diet seems to help. Also, buy as many organically grown foods (fresh produce) as you can afford. With supplementing iodine, you may get some detox symptoms at first (headache, pimples)but it gets better as you get the junk out of you and enough Iodine in you for all the body functions that require it to actually have Iodine to do their jobs.
