Latency: For HSV-1, the interval between the onset of virus exposure and symptoms (latency) is 2 to 12 days. Most people spend an average of three to six days.
Disease duration: Signs and symptoms will last two to three weeks (healing time). Fever, tiredness, muscle pain and irritability may occur.
Pain, lip soreness, burning sensation, tingling or pruritus occur before the site of infection. These are early symptoms (prodrome). Sometimes these symptoms occur before ulcers, bumps, tendon-like lesions or blisters (herpes or herpetic stomatitis) appear. Thereafter, one or more groups of painful blisters (also known as hot water blisters) or vesicles erupt or exude from a clear to pale yellow liquid, which may develop into a yellowish crust. These blisters rapidly decompose and appear as tiny light gray sores on the red base. Fever blisters are smaller than ulcers. A few days later, they became scabs or scabs, appearing drier and more yellow.
Mouth ulcers: The most severe pain caused by these ulcers occurs at the time of onset and may make diet and drinking difficult.
Pain can occur on the lips, gums, throat (causing sore throat), before or under the tongue, on the inside of the cheek, and on top of the mouth.
They can also extend their chins and necks.
The gums may be slightly swollen, red, and may bleed.
Lymph nodes in the neck often become swollen and become painful.
People in their teens and twenties can suffer from pale ulcers and gray patches on the tonsils.
