Skin redness, swelling, and itching?


Is this urticaria? From May 2nd to May 8th, I have been experiencing persistent redness and swelling that feels particularly itchy when it gets warm! This condition is present on my thighs, calves, arms, and abdomen.
The picture shows the most severe state.
On May 4th, I went to a dermatologist and received an injection.
I have been taking antihistamines and allergy medications daily, but there has been no improvement.

Medical regulations state that "a physician must personally examine a patient before administering treatment or prescribing medication..." Therefore, online diagnosis is also not permissible.
If you are experiencing significant distress, it is advisable to seek medical attention promptly.

More Info


Hives, also known as urticaria, is a common skin condition characterized by raised, itchy welts or red patches on the skin. It can be triggered by various factors, including allergens, medications, stress, and even temperature changes. Based on your description, it seems you are experiencing persistent skin redness and itching, which could indeed be indicative of hives.
The symptoms you describe—widespread redness, heat, and intense itching across various parts of your body—align with typical presentations of hives. The fact that you have been experiencing these symptoms for several days, despite taking antihistamines and receiving an injection from a dermatologist, suggests that your condition may be more complex than typical hives.
Hives can be acute or chronic. Acute hives last less than six weeks and are often linked to a specific trigger, such as food, medication, or an insect sting. Chronic hives, on the other hand, persist for six weeks or longer and may not have an identifiable cause. In some cases, chronic hives can be associated with underlying health issues, such as autoimmune disorders or chronic infections.

Given that you have already consulted a dermatologist and are on antihistamines, it is essential to continue following their advice. If your symptoms do not improve, or if they worsen, you should return to your healthcare provider for further evaluation. They may consider additional treatments, such as corticosteroids, which can help reduce inflammation and itching.
In the meantime, here are some general recommendations to help manage your symptoms:
1. Avoid Known Triggers: If you have identified any specific triggers (such as certain foods, medications, or environmental factors), try to avoid them as much as possible.

2. Cool Compresses: Applying a cool, damp cloth to the affected areas can help soothe the skin and reduce itching.

3. Oatmeal Baths: Taking a bath with colloidal oatmeal can provide relief from itching and irritation.

4. Loose Clothing: Wear loose-fitting clothing to avoid irritating the skin further.

5. Stress Management: Since stress can exacerbate hives, consider incorporating relaxation techniques such as deep breathing, meditation, or yoga into your routine.

6. Follow-Up Care: Keep in close contact with your dermatologist or primary care physician. They may want to conduct further tests to rule out any underlying conditions or adjust your treatment plan.

7. Medication Review: If you are taking other medications, discuss them with your doctor to ensure they are not contributing to your symptoms.

In conclusion, while your symptoms may suggest hives, it is crucial to work closely with your healthcare provider to determine the exact cause and appropriate treatment. Persistent skin issues can sometimes indicate more complex health concerns, so thorough evaluation and follow-up are essential. If your symptoms continue or worsen, do not hesitate to seek further medical advice.
