Hives : Chronic hives are mostly of an unknown cause but you should be evaluated by an allergist to help elucidate the cause if any.

Circadian rhythm: The body has evolved to get up in the morning and be ready for hunting at least for the male. For women the equivalence is shopping (gathering). As evening approaches, the body starts to wind down so that you can sleep. Thus everything tends to be worse towards the evening. The biologic basis? The body's adrenaline and cortisone levels drop as we get closer to the night.
