Hive Allergies

Hive allergies are evident by the presence of rashes, swelling, or bumps on the skin of the affected person. These are mostly triggered in response to an allergic reaction.

Physical Hive

Physical hive represent an exclusive sub-type of the hives that are roused by an exogenous physical stimulus instead of occurring impulsively. In physical hive, the skin becomes raised and inflamed, especially when stroked, scratched, rubbed, or slapped. The physical hive can be classified by different sources, such as thermal, mechanical, and cholinergic.

It is believed that up to thirty percent of cases of chronic hives have a physical cause. Though physical hive is not a life threatening disease, it can cause great distress and itchiness. This is not an infectious disease and is not transferred from one person to another. In many cases, rashes vanish within a few hours after appearing, and in some cases, they might stay much longer or reappear on the same or different part of the body after a short time.

Physical hives, more often than not, are triggered by scratching the skin or by wearing rough and tight clothing, wristwatches, sunglasses, highly energetic kissing, and extreme weather, etc.
