Symptoms of Sun Allergy
The symptoms of sun allergy can vary depending on the specific type of allergy. Here are some common symptoms associated with different types of sun allergies:
- Polymorphous light eruption (PMLE): People with PMLE may experience a burning or itchy rash within two hours of sun exposure. They may also feel unwell, nauseous, and may develop a headache. In some cases, small fluid-filled blisters may appear.
- Photoallergic eruption: This type of sun allergy can cause tiny blisters on the skin. The skin eruptions may spread to other parts of the body.
- Actinic prurigo: Similar to PMLE, actinic prurigo causes symptoms such as a rash, but it typically affects only the face.
- Solar urticaria: Solar urticaria is characterized by the development of hives within minutes of sun exposure.
It is important to note that each person may experience different symptoms and reactions to sun allergy. If you suspect you have a sun allergy, it is recommended to seek medical advice for proper diagnosis and treatment.
How Long Does a Sun Allergy Last?
The duration of a sun allergy can vary depending on the specific type of allergy. Different sun allergies have different timelines for resolution. For example, a rash caused by polymorphic light eruption (PMLE) typically disappears within a couple of days. On the other hand, individual hives caused by solar urticaria usually fade away within two hours. The duration of photoallergic eruptions tends to be unpredictable, while actinic prurigo follows a seasonal pattern.
