Urticaria Coping Guide: Understanding Early Symptoms and How to Relieve Itching

As spring turns to summer, fluctuating temperatures can cause sudden skin itching and the appearance of large patches of hives. This could very likely be "urticaria" (commonly known as "hives") at play. Urticaria is a common skin condition that causes intense itching during outbreaks. What are the early symptoms of urticaria? Do patients need to seek medical attention? And how can the itching be relieved? This article will comprehensively explore the causes, early symptoms, treatment methods, and key points for preventing recurrence of urticaria, helping readers to better identify and manage this allergic reaction.

There are numerous causes of urticaria, and while some patients may identify the trigger immediately, others may need to observe and record their symptoms repeatedly. Below are some of the more common triggering factors:

• Food Allergies: For example, seafood, nuts, eggs, milk, etc.
• Drug Reactions: For example, Ibuprofen, Aspirin, antibiotics, etc.
• Insect Bites or Infections: For example, colds, pneumonia, Helicobacter pylori infection, etc.
• Physical Stimuli: For example, temperature changes, sun exposure, intense exercise, sweating, etc.
• Internal Factors: For example, mental stress, emotional fluctuations, hormonal changes, etc.
• Underlying Conditions: For example, autoimmune diseases or chronic inflammation.
• Gut Health: For example, imbalance in gut microbiota.

The onset of urticaria often occurs suddenly, with some patients experiencing redness, itching, and even swelling discomfort on their skin without any prior warning. Nevertheless, the initial outbreak of urticaria still presents some typical symptoms to watch for:

• Skin Changes: The skin may suddenly develop red or skin-coloured welts.
• Welt Appearance: Welts vary in size and have irregular shapes.
• Severe Itching: The affected area feels intensely itchy, and scratching may cause the area to expand.
• Skin Texture: The skin surface may be slightly raised and feel somewhat hard to the touch.
• Angioedema: Some patients may also experience swelling of the mucous membranes around the eyes, lips, or other areas, a condition known as "Angioedema".
• Transient Nature: Welts typically subside on their own within a few hours to 24 hours and do not leave scars.

Although most cases of hives resolve on their own within a few hours, they can sometimes be a warning sign of a severe allergic reaction and should not be ignored. If you experience the following conditions, it is advisable to seek medical attention immediately:

• Persistent Symptoms: Symptoms persist for several days without relief.
• Severe Allergic Symptoms: Signs of a severe allergic reaction (Anaphylaxis), such as throat tightness, difficulty breathing, or swelling of the tongue or lips.
• Reaction to Medication or Vaccine: Suspicion that symptoms are triggered by a vaccine or medication.
• Impact on Quality of Life: Recurrent hives that affect daily life and sleep quality.
• Ineffective Treatment: Treatment results are not as expected, or medication adjustments are needed.

Seeking medical attention promptly can effectively prevent the condition from worsening, thereby safeguarding personal health.

In addition to medical treatment, when experiencing a hives outbreak, it is also important to take note of the following care tips to help alleviate discomfort and prevent recurrence.

• Apply a cold compress to the affected area: This can help relieve itching and swelling. You may use a wet towel as a cold compress or gently rinse with cold water, especially effective at the onset of symptoms.
• Avoid scratching: Scratching can stimulate the skin to release more "Histamine," causing the hives to spread further and potentially leading to skin damage or infection. Try to refrain from scratching as much as possible.
• Keep the skin dry and avoid hot showers: Hot water can cause blood vessels to dilate, potentially worsening symptoms. It is recommended to take quick showers with lukewarm water instead.

Urticaria, though common, often causes significant distress to patients during an outbreak. For effective treatment, the first step is to determine whether it is a transient acute episode or a recurring chronic issue, and then devise an appropriate treatment plan based on the severity.

Acute Urticaria: Focus on Rapid Relief

For acute urticaria, doctors typically recommend common over-the-counter antihistamines such as Diphenhydramine or Loratadine. These medications can help alleviate allergic reactions on the skin, relieving itching and rashes. In more severe cases, such as widespread hives, intense itching, or disruption of sleep, doctors may prescribe stronger antihistamines or even short-term oral corticosteroids to quickly control the inflammatory response.

Chronic Urticaria: Requires Long-Term Management

Chronic urticaria is characterised by recurrent episodes, often linked to an imbalance in the body's immune system. For such patients, in addition to regular antihistamine use, treatment plans may include:

• High-Dose Antihistamines: Used long-term to regulate allergic reactions.
• Oral Corticosteroids: Primarily used to control acute flare-ups, but due to significant side effects, they are not recommended for long-term use.
• Biologics: Such as anti-IgE (Immunoglobulin E) medications, specifically designed for chronic urticaria cases with poor response to other treatments, targeting and suppressing abnormal immune system reactions at the root.

Urticaria, though common, can in some cases be a severe allergic reaction, potentially requiring emergency medical attention or hospitalisation. If you have suitable medical insurance in place, you can be admitted to a private hospital during unexpected situations without worrying about exorbitant medical costs, avoiding long waiting times at public hospitals and receiving appropriate treatment as soon as possible.

To effectively manage urticaria, in addition to medical treatment, daily care is equally important. Implementing the following measures can not only enhance treatment outcomes but also help in long-term condition stabilisation and reduce the likelihood of recurrence.

• Avoid allergenic foods: Common allergenic foods include seafood, nuts, eggs, and dairy products. It is recommended to keep a food diary to identify and avoid potential allergens.
• Wear loose and breathable clothing: This helps to minimise friction and irritation on the skin. Opt for pure cotton materials, which are more comfortable to the touch and help keep the skin dry.
• Stay away from known triggers: These may include hot environments, intense sunlight, stress, certain medications, or contact allergens such as metals and chemicals. Avoid environments that are likely to trigger symptoms as much as possible.
• Maintain a regular routine and emotional stability: Sufficient sleep, a consistent daily schedule, and effective stress management all contribute to stabilising the immune system, thereby reducing the risk of recurrence.

Urticaria, commonly known as hives, is not contagious. It is a skin condition triggered by an abnormal reaction of the immune system, primarily related to allergies, individual constitution, and environmental factors, rather than caused by pathogens such as viruses or bacteria. Therefore, it does not pose a risk of transmission. In other words, even close contact with a patient or sharing items with them will not result in contracting urticaria.

It is worth noting that certain infections caused by viruses or bacteria (such as colds or flu) are contagious, and these infections may act as triggers for urticaria. In such cases, what others might contract from the patient is the cold or flu, not urticaria itself. Hence, if an outbreak of urticaria is accompanied by symptoms of infection such as fever or sore throat, it is advisable to seek medical attention promptly to diagnose and address the underlying infection.

Urticaria (also known as hives or welts) is an allergic skin condition often characterised by the sudden appearance of red, swollen, and itchy wheals on the skin. These wheals vary in size and have irregular shapes, typically resolving on their own within 24 hours.

Acute Urticaria

Acute urticaria develops rapidly and is usually triggered by external stimuli such as medications, food, insect bites, or infections. Most cases resolve within a few hours to a few days; due to the clear symptoms, it is relatively easy to identify the triggers and subsequently avoid contact with them.

Chronic Urticaria

Chronic urticaria refers to recurring symptoms lasting more than six weeks. Its causes may be related to immune system imbalances, autoimmune diseases (such as lupus or thyroid issues), or imbalances in gut microbiota. The treatment duration is longer, sometimes taking months or even longer to achieve relief.
