What is the direct answer?

What does this question mean?

The lesion often begins with tingling or burning, followed by grouped fluid-filled blisters that crust. Herpes simplex virus remains in nerve tissue and can reactivate; touching the sore can transfer virus to the eye or another person.

What can you do next?

Follow the product label for a pharmacy antiviral cream if it is suitable for you, keep the area clean, wash hands after touching it, and avoid kissing or sharing utensils while the sore is active. Do not pick the crust.

When should you seek dental care?

Seek medical care for an eye symptom, widespread lesions, severe illness, a sore that is not healing, or frequent outbreaks. Prompt advice is also important for people with weakened immunity or a newborn contact.

What should you ask the dentist?

Ask a pharmacist or clinician whether an antiviral is appropriate, when prescription treatment is needed, and how to prevent spread to the eye or another person.
