Urticaria appears as wheal/hives and redness typically accompanied by itchiness and resolved within 24 hours.
It may or may not be associated with angioedema (swelling over eyes, lips, throat, extremities, genitalia, etc.)
It may occur spontaneously or be induced by specific stimuli such as food, environmental triggers, temperature changes, sweating, physical pressure, etc.
A severe form of urticaria called Anaphylaxis (involvement of systemic symptoms such as difficulty breathing, abdominal cramps, increased heart rate, and loss of consciousness) may require immediate medical attention.
Treatment
- Allergic test
- Avoid the stimuli
- Regular antihistamines usage
- Biologic such as Omalizumab
