What should I do if blisters appear after sunburn?

If blisters develop after sunburn, follow these steps for treatment: 1. Cold compress: For small blisters, apply a cold compress using ice wrapped in gauze, or rinse the area with cool water to help relieve pain and reduce the blister. 2. Disinfection and care: Seek medical attention promptly. A doctor should disinfect the skin around the blister and use a sterile needle to drain the fluid. Avoid self-treatment to prevent infection. 3. Medication: Under medical guidance, oral antihistamines such as levocetirizine hydrochloride tablets or loratadine tablets may be taken to help reduce skin inflammation and itching. 4. Keep the skin clean and avoid scratching. During treatment, maintain a light diet and avoid spicy or irritating foods.
