How is urticaria diagnosed?

If you are experiencing symptoms of urticaria, you should visit a doctor. They will ask you questions about your symptoms. They may then perform a physical exam of the skin.

They may also take a small amount of a fluid from the area of the urticaria and test it for the presence of an allergen. This is called a skin prick test.

If you have an allergic reaction, your doctor will ask you questions about your symptoms and your medical history.

They will also perform a skin prick test and ask you to apply a small amount of the suspected allergen to the forearm. If a substance causes an allergic reaction, a wheal or a rash will appear at the site of the skin prick.

They will also perform a patch test to determine whether a substance causes a reaction. They will apply the substance to the back and measure the skin’s reaction.

How is urticaria treated?

Treatment for urticaria depends on the cause. It is usually not serious and will go away on its own.

If you have a viral infection, you may be able to treat your symptoms at home. It is also possible to take over-the-counter (OTC) medications.
