Angioedema
You will also notice that Angioedema is another condition the gets detected from individuals suffering from Hives. It’s a condition that arises from allergic or nonallergic causes which involve leakage of blood fluids in the deep blood vessels within the submucosal or the subcutaneous layers. The hives from such a condition sometimes get more painful where it can last for more than 24 hours and leave some bruises and marks after healing which will eventually heal. The condition may escalate and turn much more, and when this happens, it results in urticarial vasculitis but will also heal and fade away. [2]
