My ige level has been high than normal since the last 8 to 9 years. Situation indicates that I am allergic to foods like dairy products etc. Then I decide to not consume it. My vitamin d and b 12 are low and hemoglobin too. My lifestyle is bad. I know these are the problems will always prevent me getting cure from my allergic condition. As fast as my allergic reaction is concerned, I experience tingling which also relates to vitamin deficiency. But whenever I think too much about my issues I often experience hotness and redness on chest and other parts. Sometimes hives appear due to my stress or any reason. Last year my skin prick test shows that I am not allergic to any food etc. My tingling issue connected to vitamin loss. But what about hives and redness or hotness on skin? Is it also related to vitamin deficiency and stress? If yes then it's ok. If it is an indication of urticaria issue in body then I do not want to remain confused at all. Is there any ideal test which can ascertain that whether I have urticaria or not? I would go for this test surely? And tell me about histamine test? Is histamine test similar to ige test or does it have another purpose? Please send your reply.
