L55.9

Clinical Causes: Prolonged exposure to direct sunlight, especially during peak hours (10 a.m. to 4 p.m.) Not wearing protective clothing or hats Absence or inadequate application of sunscreen with sufficient SPF Exposure to reflective surfaces like water, snow, or sand that intensify UV rays Certain medications that increase skin sensitivity to sunlight (photosensitizing agents)

Key Symptoms: Redness and inflammation of the skin Pain or tenderness when the affected area is touched Swelling of the skin Warmth or burning sensation in the affected area Dry, peeling skin as the burn heals In more severe cases, blisters and swelling Possible nausea or dizziness if the sunburn is extensive

Diagnosis Path: Diagnosis of sunburn is primarily clinical, based on a physical examination of the skin and patient history of recent sun exposure. Healthcare providers may inquire about the duration of sun exposure, skin symptoms, and any use of photosensitive medications. In some cases, especially with severe burns or suspected complications, additional assessments or skin biopsies may be performed to rule out other skin conditions or infections.

Treatment Protocols: Treatment focuses on alleviating symptoms and promoting skin healing. Common approaches include: - **Cooling the skin:** Applying cool compresses or taking cool baths to reduce heat and pain. - **Moisturizing:** Using aloe vera gels or other soothing moisturizers to hydrate the skin. - **Pain relief:** Taking over-the-counter analgesics such as acetaminophen or ibuprofen to manage discomfort. - **Hydration:** Drinking plenty of fluids to prevent dehydration. - **Avoiding further sun exposure:** Staying out of the sun until the skin heals. - **Protective measures:** Future prevention through the use of broad-spectrum sunscreens, protective clothing, and avoiding peak sun hours. Severe cases with blistering or extensive skin damage may require medical attention, including prescription medications or wound care. If complications like infection or severe reactions occur, prompt consultation with a healthcare professional is recommended.
