Physical Urticaria is a disorder in which exposure to heat, cold, or contact with chemicals or plants causes red (erythematous) allergic skin sores and itching (pruritus). The medical community refers to these as wheals, and they can be anywhere between a few millimetres and a few centimetres in size.
Cause of Physical Urticaria
- In most situations, the underlying reason for physical urticaria is unknown.
- Some medical professionals think that an auto-immunological process can be the cause of Physical Urticaria.
Diagnosis available for Physical Urticaria
- The methods most commonly used to diagnose physical urticaria are the patient history and physical examination.
- The diagnosis may be verified with a challenge if there is a history of responses to physical triggers.
- The tricky part is applying the alleged agent like ice or light to the skin in the hopes of eliciting a reaction.
Treatment (Standard Therapy) for the Physical Urticaria
- The majority of Physical Urticaria cases respond well to over-the-counter medications that reduce the allergic reaction.
- The physical cause of the reaction must be avoided and protected from.
- In addition to antihistamines, this can also refer to a group of medications known as H2 blockers.
- An oral antihistamine can typically reduce symptoms like itching and swelling.
- Unless absolutely necessary, the more potent systematic (intravenous) corticosteroids should be avoided.
