Non disseminated Candidiasis.
You have just written a textbook diagnostic for this.
The yeast Candida Albicans morphed into the pathogenic fungal form. 'Mycelial Candida'.(Did this start when you went on the pill or started using steroids?)
The bloating, chronic eczema are IBS and the associated histamine reaction.
This is easy to cure with Nystatin. You need 2 consecutive courses(28 days) of 2 million IU per day, that is 5 drops 4 times a day. It tastes vile and requires your compliance.
The AtkinsPaleo diet will starve the Candida, but not kill it.
It is a Sugar and carb free diet. Candida live on sugars and carbs.
You can take 180mg Fexofenadine will help calm it down until you can get Nystatin, but is not a cure and not a long term solution.
Fexofenadine will work as it prevents histamine from forming, and it is histamine that is causing the chronic body eczema.
Teaspoon of cod liver oil with every meal is beneficial too.
I study this. PM for more info. Ask your doctor to email me if that would help. There is candidiasis@yahoogroups too.
Isuspect you will have great difficulty in getting your doctor to believe this is the cause as American doctors have a dogma against this diagnosis. (An Austrian or Swiss doctor would have you cured in a week)
