Hello,
Hives are itchy and raised, red welts that develop on the surface of the skin, involving only the two skin layers. Urticaria is another word for hives. Urticaria is sometimes accompanied by
angioedema, which is swelling deeper in the skin. A presumptive trigger, such as a drug, food ingestion, insect sting, or infection, may be identifiable in patients with new-onset urticaria, although no specific cause is found in many cases, particularly when the condition persists for weeks or months.
Your doctor will need to ask many questions in an attempt to find the possible cause of hives or angioedema. Since there are no specific tests for hives or the associated swelling of angioedema testing will depend on your medical history and a thorough exam by your doctor or
dermatologist. A skin test may be performed to determine the substance to which you are allergic. Routine blood tests are done to determine if a system-wide illness is present.
The best treatment for hives and angioedema is to identify and remove the trigger, but this is not an easy task. Antihistamines are usually prescribed by your doctor to provide relief from symptoms. Antihistamines work best if taken on a regular schedule to prevent hives from forming in the first place. You can add cool compresses or wet cloths to the affected areas, try to work and sleep in a cool room, wear loose-fitting lightweight clothes.
Chronic hives may be treated with antihistamines or a combination of medications. when antihistamine doesn't provide relief, oral
corticosteroids may be prescribed. For severe hive or angioedema, an injection of
epinephrine (
adrenaline) or a cortisone medication may be needed. See your doctor right away if you have
difficulty breathing,
dizziness, wheezing, swelling of the tongue, lips or face or tightness in the chest.
Hope I have answered your query. Let me know if I can assist you further.
