For the past year, I have been suffering from Chronic Idiopathic Urticaria. At first, the hives were quite sporadic, occurring once or twice a month, but since December 09, they've been occurring daily. They appear at different areas on my body (including my palms), but rarely on my face, and usually last 2-3 hours. I've been tested for allergies, both food and environmental, and the only positives were certain molds, trees, and grasses.
