Sudden Raised Bumps on the Skin: What Is Urticaria?
Urticaria, commonly known as hives, is a common skin condition characterized by sudden episodes of redness, raised bumps and intense itching on the skin. These raised lesions often appear quickly, may change location and can disappear within 24 hours without leaving a mark.
Urticaria may occur as a single episode in some people, while in others it can become a recurrent or long-lasting condition. Itching, a burning sensation and raised areas on the skin can significantly affect daily comfort and quality of life.
At Dr. Seher Arı Dermatology Clinic in Göktürk, Istanbul, complaints related to urticaria and hives are evaluated by considering the duration of the episodes, triggering factors, accompanying swelling and the person’s general health status.
Not Just Temporary Spots, But the Skin’s Alarm System
The raised lesions seen in urticaria are usually red or skin-colored, itchy and slightly swollen plaques. They may sometimes remain limited to small areas, or they may merge to form larger raised patches.
Urticaria symptoms usually begin suddenly. One of the typical features is that the raised bumps may change location, disappear within a short time and reappear in a different area.
Common signs of urticaria may include:
- Sudden itchy raised bumps on the skin
- Redness and a sensation of warmth
- Rashes that change location
- Plaques that may disappear within 24 hours
- A burning or stinging sensation
- Swelling of the lips, eyelids, hands or feet in some people
Angioedema: When Swelling Comes from Deeper Layers of the Skin
Angioedema is a type of swelling that develops in the deeper layers of the skin. It may occur together with urticaria or appear on its own. It is most commonly noticed around the eyelids, lips, face, hands, feet and sometimes inside the mouth.
In angioedema, a feeling of tightness, burning, stinging or pain may be more prominent than itching. The swelling usually takes longer to resolve compared to the raised bumps of urticaria.
If swelling of the lips, tongue, throat or inside the mouth is accompanied by shortness of breath, difficulty swallowing or a change in voice, emergency medical care should be sought.
What Happens When Histamine Is Released?
One of the main mechanisms in urticaria and angioedema is the release of substances such as histamine from mast cells in the skin. Histamine release may cause blood vessels in the skin to widen, fluid to leak into the surrounding tissue and redness, swelling and itching to develop.
This reaction may sometimes be triggered by infections, medications, foods, stress or physical factors. However, in some cases of chronic urticaria, a clear cause may not be identified. For this reason, a detailed medical history and dermatological evaluation are important for each patient.
7 Common Factors That May Trigger Hives
Urticaria may occur with different triggers in each person. In some people, an episode may develop after an infection, while in others it may appear after medication use, stress or physical contact.
Common factors that may trigger urticaria include:
- Colds, flu and upper respiratory tract infections
- Painkillers, antibiotics, muscle relaxants and some blood pressure medications
- Alcohol, certain foods and food additives
- Allergens such as house dust and pet dander
- Intestinal parasites
- Excessive stress
- Physical factors such as pressure, cold, heat and exercise
Triggering factors are not the same for everyone. Therefore, foods consumed, medications used, recent infections and environmental exposures before a urticaria episode should be evaluated together.
Acute or Chronic? Duration Changes the Treatment Plan
Urticaria may be short-term, known as acute urticaria, or it may be considered chronic urticaria when it lasts longer than 6 weeks. Acute urticaria may often be associated with more identifiable triggers such as infections, medications or foods.
In chronic urticaria, however, a clear cause may not always be found. In some people, immune system-related mechanisms may play a role. For this reason, in long-lasting urticaria complaints, it is more appropriate to proceed with an evaluation by a dermatology specialist instead of applying unnecessary restrictions.
The First Step in Treatment: Identifying and Controlling the Trigger
The aim of urticaria treatment is to reduce episodes of itching and raised bumps, assess the risk of angioedema and improve the person’s quality of life. The treatment plan is created according to the duration and severity of the condition and the triggering factors.
Approaches that may be considered in urticaria treatment include:
- Identifying foods, medications or environmental factors that may act as triggers
- Avoiding unnecessary medication use
- Using antihistamine treatments recommended by the doctor regularly
- Evaluating additional treatment options in severe or resistant cases
- Assessing risk status in the presence of angioedema
- Creating a regular follow-up plan for chronic urticaria
How long medications should be used in urticaria treatment may vary from person to person. Therefore, treatment should be continued as recommended by the dermatology specialist.
Food Restriction Is Not Always the Solution
People with urticaria often suspect foods first. In some people, certain foods or additives may increase attacks; however, not every case of urticaria develops due to food allergy.
Unnecessary and long-term dietary restrictions may reduce quality of life. Therefore, which foods are truly triggering should be determined through the person’s medical history and a doctor’s evaluation.
Fish, eggs, shellfish, foods containing additives or alcohol may increase symptoms in some people. However, this does not apply to everyone.
Frequently Asked Questions About Urticaria
Is urticaria contagious?
No. Urticaria is not contagious. It does not spread from person to person through contact. However, some conditions that may trigger urticaria, such as infections, should be evaluated separately.
How long do hives last?
Acute urticaria may be short-term. Episodes lasting longer than 6 weeks are considered chronic urticaria and may require regular dermatological follow-up.
Is urticaria an allergy?
Urticaria may sometimes develop due to allergic causes; however, not every case of urticaria is an allergy. Infections, medications, stress and physical factors may also trigger urticaria.
Is angioedema dangerous?
It may appear as swelling of the eyelids or lips. However, if there is swelling of the tongue, throat or inside the mouth, shortness of breath or difficulty swallowing, emergency medical care should be sought.
Does urticaria treatment vary from person to person?
Yes. Treatment should be planned according to the duration and severity of urticaria, triggering factors, the presence of angioedema and the person’s general health status.
