Hives, also known as urticaria, are itchy bumps and raised patches that develop when the body releases histamine. The causes of hives can vary and may include:
- Allergic reactions to food, insect bites or stings, latex, medication, pet dander, plant pollen, or environmental factors like pollen, dust mites, or chemicals.
- Overreactions to heat, sweat, cold, sunlight, emotional stress, or physical pressure on the skin.
- Infections such as colds, strep throat, urinary tract infections, or even COVID-19.
- Medications like non-steroidal anti-inflammatory drugs (NSAIDs) or antibiotics.
- Other factors such as scratching or pressing on the skin, tight clothing, or a problem with the immune system.
Its important to identify the cause of hives to avoid them in the future and seek medical attention if complications such as angioedema or anaphylaxis occur.
