Acute conjunctivitis is usually caused by bacterial infection, also known as pink eye. In the early stages of treating acute conjunctivitis, it is necessary to choose sensitive antibiotics for anti-infection treatment, such as antibiotic eye drops. Frequent application can alleviate symptoms. Generally, it is not recommended to apply heat as this can easily lead to the spread of local infection and may also lead to cross-infection. However, appropriate local cold compresses can be applied, as acute conjunctivitis is characterized by symptoms such as redness, swelling, heat, pain, and increased secretions. Local cold compresses can help reduce symptoms and relieve discomfort.
