What causes hives?

Hives are a condition that causes itchy, raised rashes on the skin and can usually be caused by:

1. Allergic Reactions: Common allergens include certain foods (such as seafood, nuts), pollen, animal dander, and insect bites.

2. Medications: Certain medications, such as antibiotics, can cause hives.

3. Infections: Bacterial or viral infections can cause hives.

4. Stress: Physical or emotional stress can trigger hives.

5. Temperature Changes: Your skin can also react this way to sudden changes in cold or heat.

To better understand your medical history (anamnesis), I need the answers to the following questions:

• How long have you had hives?

• What conditions or foods may trigger hives?

• Are there any other symptoms besides hives (e.g. shortness of breath, swelling of the lip)?

• Have you started taking any new medications recently?

Based on this information, I can make more detailed recommendations. If the hives are severe or accompanied by other symptoms such as shortness of breath and swelling, I recommend that you consult a healthcare professional immediately. I am now providing guidance on which medical branch you should consult regarding the condition you have described.
