Hi Cory, I never went to my doctor about the rashes. As a matter of fact, I never went to the doctor at all when I was thin because I was afraid he would ask about my diet. I was embarassed. I knew that eating that way was not quite right.I think it was due to a yeast infection that was not localized to my scalp & genital area (where it is commonly found). I tried everything-Tea tree oil, iodine, the cream that comes with a Canesten pack, nothing worked! I know now after reading Atkins book that it was due to the overabundance of sugar in my body. A typical day for me waould be pasta (white of course), white bread, 10 cups of coffee with double sugar & skim milk, sugar sweetened fruit drinks, lots of fruit (esp. bananas) and other carb -laden low fat foods. Since starting this WOE I've not had ANY of these symptoms & I feel fantastic. You say this is your 2nd time around? How long (this time) have you been on? It might be detergents, the cleansers you are using for yourself or your home, air fresheners... the list is numerous as I'm sure you know. Maybe your MD could refer you to an allergy clinic or a dermatologist. You may have eczema or psoriasis which can develop at any stage of life. All I know is that when I cut ALL carbs out of my diet there were no more problems.--Good luck!!!Nolly
