Urticaria shows as raised, intensely itchy wheals that appear suddenly, migrate across the body and each vanishes within 24 hours; swelling of lips, tongue or throat signals dangerous angioedema.
The wheal (hive) - the signature lesion:
Angioedema - the deeper swelling: in about 40% of patients, swelling goes deeper than the skin - puffy lips, swollen eyelids, swollen tongue, or swelling of hands, feet or genitals. It is less itchy, more aching or tight, and takes a day or two to settle. Angioedema of the tongue or throat is dangerous.
Emergency symptoms - anaphylaxis; call 112 immediately:
Symptoms that suggest it is NOT simple urticaria: individual spots lasting over 24-48 hours in the same place, burning or pain rather than itch, bruising as lesions fade, fever and joint pains - these warrant a doctor looking for other conditions (like urticarial vasculitis).
Course: acute urticaria settles within days to six weeks. Chronic urticaria (beyond six weeks) comes in waves - some patients are clear for months between episodes, others itch daily; the average duration is years, but it does eventually burn out in most people.
Remember: migrating itchy wheals that each vanish within a day are classic hives - annoying but manageable. Tongue, throat or breathing involvement is 112, every single time.
Classical Sheetapitta descriptions capture the migrating, itchy, wind-like quality well. The angioedema emergency, though, belongs to adrenaline and emergency care - no traditional measure intervenes fast enough.

Urticaria (hives) happens when mast cells in the skin release histamine - triggered by foods, medicines, infections or physical factors, though chronic hives often have no findable cause.
Acute urticaria is cured by removing its trigger and a short antihistamine course; chronic urticaria is controlled (not cured) with daily antihistamines for months until the disease burns out.
Exercise is fine with most hives and stress-calming yoga genuinely helps chronic urticaria - but sweat and heat trigger some types, and never exercise through swelling or breathing symptoms.
Non-sedating antihistamines (cetirizine, loratadine, fexofenadine) are the mainstay - taken daily for chronic hives; steroids are short-course rescue only, and omalizumab helps stubborn chronic cases.
Only ban foods with a proven personal reaction; blanket diet bans in chronic urticaria are useless and harmful - though a short low-histamine trial can help some, and alcohol often worsens hives.
Ayurveda treats urticaria as Sheetapitta with neem, haridra and diet rules; these may soothe itch, but antihistamines are the proven mainstay and throat swelling is never a herbal situation.
