I understand your concerns. I've been there myself. Your symptoms look very much like severe iodine deficiency.
See our testimonials, chapter Prostate for cures to Prostate/ejaculation problems. Including my own. http://tinyurl.com/iodine-testimonials

Iodine is required by every cell in our body, and especially by our skin & organs.
Nail fungus - Spray SSKI iodine to your nails once a week until gone in a small hand sprayer.
Dandruff - Apply SSKI to the scalp with the eyedropper once a week until it disappears. Towel Dry. Normally one or 2 treatments last many months.
and your thyroid is especially in need of iodine to function properly. Have you taken your body temp? If you are consistently below 98.6 degrees, then you are likely to have low thyroid function. See Thyroid in the above testimonials. This is usually accompanied by cold hands & cold feet.
