Acute urticaria manifests as sudden severe itching of the skin, quickly followed by hives of various sizes. In severe cases, symptoms can include palpitations, restlessness, nausea, vomiting, and other signs of anaphylactic shock. Chronic urticaria is characterized by recurrent outbreaks of hives, often lasting for several months or years.

How to treat chronic urticaria?

Chronic urticaria often utilizes antihistamine medications to control symptoms, combined with Traditional Chinese Medicine (TCM) and differential diagnosis and treatment. Treating chronic urticaria generally requires long-term use of antihistamines, sometimes for two or three months, or even up to six months, a year, or more. Typically, treatment involves the combination of two or more types of antihistamines. For cases of chronic urticaria where antihistamines are ineffective, immunosuppressants may be used to adjust the body’s immune state, thus controlling the outbreaks of chronic urticaria. Chronic urticaria is a long-term, slow process that cannot be resolved quickly, so it is important to try to identify the triggering factors of chronic urticaria, or to identify specific allergens. However, finding the allergen is usually challenging because many patients with chronic urticaria have conditions that are also related to their own immune status.

Difference between Flat Warts and Hives

Flat warts and hives are two different diseases with significant differences. First, the causes of these diseases are different. Flat warts are caused by human papillomavirus infection, while hives are related to allergies, usually caused by exposure to an allergen, and the specific cause needs to be determined through testing, with many cases having an unknown cause. Secondly, their treatment methods are also different; flat warts are often treated with lasers, cryotherapy, antivirals, etc., while hives are commonly treated with anti-allergy methods.

How should hives be treated?

Urticaria is divided into acute and chronic types. Antihistamines are the first choice of treatment for acute urticaria. If the condition is severe and antihistamines are ineffective, corticosteroids can be used to control the condition. The fundamental treatment for chronic urticaria is to remove the cause, and specific medications should be used under the guidance of a doctor.

The difference between papular urticaria and urticaria

Papular urticaria is an allergic reaction caused by direct contact with irritants or insect bites such as mosquitoes. The cause of the disease is relatively accurate, and treatment typically involves disinfecting clothes, bed sheets, and duvet covers by exposing them to sunlight, avoiding contact with small animals, and common antiallergic medications can cure it quickly. The causes of common urticaria are more complex and often unclear; identifying the allergens usually requires allergy tests in hospitals, and the treatment is more complicated than that for papular urticaria. Common antiallergic drugs can cure it in the short term. However, some cases of urticaria that enter a chronic phase can be very troublesome to treat, with lengthy treatment times and poor outcomes.

What should not be eaten with hives?

Patients with urticaria have individual differences in their physical constitutions, and not everyone is allergic to the same foods. However, some foods have a higher likelihood of causing allergies, such as seafood, shrimp, crabs, silkworm pupae, beef, lamb, dog meat, various exotic birds and game, fruits like mango, pineapple, durian, and lemon, as well as various food additives. Additionally, spicy and stimulating foods and alcoholic beverages can aggravate allergic reactions and should be avoided as much as possible. Patients who frequently suffer from urticaria may consider undergoing allergen testing to identify which foods trigger allergic reactions. However, the allergen doses used in tests are very small and many factors can affect the results, hence the test outcomes may not fully reflect the actual situation within the patient's body. Moreover, the variety of foods tested is limited, and foods not tested could still potentially trigger urticaria in patients.
