Body rash about 12-24 hours after eating carbohydrates

[Dominix7]

Hello everyone,

I have a similar problem to the one discussed here, however NOT the same:

A few months ago I started developing rash all over my body. At first, there were only small spots on my arms, however after 2 months it started appearing all over my body. The rash is like hives, however it's irregular: it mostly appears on my palms and face, but also on the front- inner part of my thighs (near knees), back of my calf, my back (only my hips so far), as well as arms and forearms... Recently, even skin on my head. In some places it's symmetrical (hips, thighs), in others it develops in random places (arms and hands). The type of carbs doesn't matter - rice, sugar, wheat, buckwheat, barley, all have the same impact. Similarly, alcohol seems to have the same effect, no matter the type.

Firstly, I stopped eating carbs completely (as far as I could), and cut down alcohol to zero. This helped and after 4-5 days my skin got back to almost-normal (some white spots where it was destroyed the most).

At first I thought it's candida, but I rejected it for the following reason: My body reaction of eating carbs (even huge quantities, with beer or other alcohol) starts about 12 to 24 hours after consumption: it starts with itching in certain places and then another 12-24 hours Iater I develop a rash in these spots. Moreover, since I have diagnosed atopic dermatitis I treat these places with Protopic, which, by locally decreasing the immunity of the skin would only make it worse - however, it does help and the rash slowly disappears.

My next step in diagnosis were allergic tests - but after testing all allergens (food) it turned out I'm not allergic to any of them  (histamine was positive, so the test was ok).

I visited the dermatologist as well, but she was unable to diagnose anything other than atopic dermatitis.

My last try was the nervous system - A year ago I had a traumatic experience (witnessed death of my partner), and the rash appeared about half a year later. Therefore after a contact with a psychiatrist I started taking some mild benzodiazepine (not available in North America, similar to valium). It had no effect on my perception (minimal dosage), but all the rash disappeared and I could eat carbs freely. Since this kind of medicine can not be taken long term I withdrew it (no withdrawal symptoms) after about 3 weeks. But the rash "slowly" came back over a period of a month / month and a half  - I had a few weeks of rest, even when the medicine stopped working, but now it's back.
Just to add: I have no psychological issues: no depression, mood swings or similar (nor I did in the past).

Now the doctor prescribed me Fluoxetine (20mg/day) + vitamin b3 for 2 months, but since it takes some time till it starts working I'm wondering: can this diagnosis be right? Have anyone witnessed similar problem? What kind of additional tests should I / could I make now?

Your situation is very similar to mine . I developed intolerances to all Carbohydrates after a series of traumatic events (my partner had a cardiac arrest right in front of me, after he got better he left me). I have been desperate to find a cause and the Indian traditional medical doctor also concluded that it is due to emotional trauma. Funny thing is when I am very happy the rashes doesn’t come.
