For nearly a year I'm suffering from some sort of allergy. It began with itching in my palms and spread all over. If I took benadryl, it would go away. Tired of this and the drowsiness associated with Benadryl I went to my doctor. They insist it is some kind of dermatitis; but unless I take anti histamine, the itching and the hives (which my doctor thought was dermatitis) continue. I insisted they give me Zyrtec, but I got Allegra instead which turned out to be just as good. Now I keep Allegra with me all the time. I stopped taking every morning, instead take as soon as I get first symptoms. 90% of times my palms start itching (I can see them turn reddish). A few times my soles start itching. If I don't take allegra at this time, soon I scratch like crazy and hives appear all over. To isolate, if there is something specific I'm allergic to has become difficult. I had this symptom pop up, at home, on hikes, another towns, in car, someones home, on the way to their home, in shopping mall ... you name it. I get this way once every alternate day or at least twice a week. I would like to know if anyone knows anything about this and suggest what I should do.
