4. Allergic Reactions: Hives and Red Patches
What It Means
An allergic reaction can cause hives (urticaria)—red, raised, and itchy welts that appear suddenly. The reaction can be mild or severe, depending on the trigger.
Possible Causes
- Food allergies (e.g., nuts, shellfish, dairy)
- Medication reactions (antibiotics, NSAIDs)
- Insect bites or stings
- Contact allergies (soaps, cosmetics, perfumes)
When to Seek Help
If red dots or hives are accompanied by difficulty breathing, swelling, or dizziness, seek emergency medical care immediately, as it may indicate anaphylaxis, a life-threatening allergic reaction.
5. Eczema: Red, Dry, and Itchy Skin
What It Means
Eczema (atopic dermatitis) is a chronic skin condition that causes red, inflamed, and itchy patches. The skin may become dry, cracked, or scaly over time.
Possible Causes
- Genetics and family history
- Skin irritation from soaps, fragrances, or detergents
- Allergies (food or environmental triggers)
- Weather changes (cold, dry air)
When to Seek Help
If your eczema symptoms are severe, persistent, or lead to skin infections, consult a dermatologist for treatment options.
