A.

In recurrent herpes, sores start as inflamed red spots that swell and become fluid-filled forming blisters. The blisters eventually collapse and form an ulcer. This will take two to three days. It often takes seven to 10 days before these ulcers completely disappear and the skin returns to normal.

In primary herpes, the healing process usually takes two to three weeks, but skin pain can last for one to six weeks.
