What causes skin rashes on exposure to sunlight?

Question

Hello doctor,

I need your assistance. For three weeks, whenever I am doing exercise and feeling hot or going out in sunlight, rashes occur on my body, and after going into an air-conditioned room, it goes away. I need suggestions and medication. I only have ringworm infections in two areas. Besides that, there is no problem. It is happening sometimes, but after taking Atarax, the problem resolves.

Hello,

Welcome to icliniq.com.

I can try to provide some general information to help you.

It sounds like you may be experiencing a condition called exercise-induced urticaria or heat urticaria. Urticaria is a type of allergic reaction that causes red, itchy welts or hives on the skin. Here are a few suggestions that might help:

1. Avoid triggers: Try to avoid activities or situations that cause the rashes to appear, such as excessive heat, sunlight, or intense exercise. Gradually increase the intensity and duration of your workouts to see if the symptoms improve.

2. Stay cool: Wear loose, breathable clothing and exercise in a cool environment. You can also apply a cold compress or take a cool shower after exercising to help reduce symptoms.

3. Take antihistamines: Over-the-counter antihistamines can help relieve itching and reduce the appearance of hives. However, it is best to consult with a doctor or pharmacist to determine the most suitable antihistamine for you, like Levocetirizine.

4. Consult a dermatologist: If the symptoms persist or worsen, it would be best to seek professional medical advice. A dermatologist can assess your condition and provide appropriate treatment options, such as prescription-strength antihistamines or topical creams.

Take care.

Regards.
