I posted last month and did more research and want to share what I found. I hope to post again after I've done more research and tried a few things.
What I think most of us have is Hypoglycemia and Anxiety. Hypoglycemia is the body's inability to properly regulate blood sugar levels, causing the level of sugar in the blood to be too low or to fall too rapidly.
Someone had mentioned on another blog that they have a Metobolic restriction problem, meaning their body has trouble beaking down sugar. It instantly reminded me of something similar that my doctor said to me last week after my blood work. He said something about my body not breaking down sugar properly, but it wasn't major and could have been caused by me drinking a glass of juice the night before my blood work.
Well turns out Hypoglycemia is almost impossible to test for and so I'm not surprised my doctor completely ignored my blood work results. I recommend doing some reading and someone mentioned a book "Hypoglycemia for Dummies". It's all about changing your diet and getting your body back to metabolizing sugar normally. The glandular imbalances that result, as the glands struggle to regulate the sugar level, cause their own symptoms - especially high adrenaline. So your body is producing extra andrenaline that comes out as anxiety and a rash for some people.
Sometimes changing your diet is difficult so I wanted to include all the important information I found on this nervous rash.
Names that I came across for this rash are: Flushing (using occurs during sex though), Erthema, Seborrheic Dermatitis which is treated with Hyracortisone or washing your chest with an anti-dandruff shampoo to kill yeast (may be worth a try), Dermagraphism, and Andrenergic Manifestations. I recommend reading up on these to see which one fits your symptoms best.
Surgery I hear can be an option, but costing $6500. I also read that it doesn't completely get rid of the blotching on the chest, but is mostly for facial blushing. Google blush free surgery for websites.
There are a few medications that kept coming up including: Inderas or generic Propanolol ER, BetaBlockers, Lacitrex (for hives), Zyrtec, and Cetapres Patch (high-blood pressure). Pretty much these are for allergies but some people have results when using them. Side effects do include being tired, but I heard good things about Inderas.
Some natural treatments I heard about are: Fish oil, TrueCalm, Magnesium, St. Johns Wort, and Preparation H that can be rubbed on the chest. Haven't tried any of them, but these are inexpensive and may be worth a try.
Some other notes: This is not a hormonal thing. I read about a man getting this and even saw a MenForum with this topic being discusssed. I found people use DermaBlend makeup and spray tanning to hide the rash. I also hear not drinking caffeine helps probably because it's not increasing your andrenaline. Exercise helps to decrease your extra andrenaline.
