The typical victim suffers three or four such flareups each year, Dr. Straus said, but those most severely afflicted may experience 12 to 16 recurrences a year, a rate that often destroys social and marital relations, disrupts job performance, and causes depression in many individuals. Oral herpes causes tingling or painful fluid-filled blisters on the edge of the lip where it meets the skin of the face ( cold sores’). From time to time flare-ups can occur. Herpes Simplex Virus 1 (HSV-1) usually causes cold sores and eye infections. Stress, fatigue, sunlight, surgery, illness, the use of certain drugs like steroids, and certain foods are all factors that may make the herpes virus flare up again, causing a herpes-related illness.
Herpes of the eye, or ocular herpes, is caused by the herpes simplex virus. This second flare-up could come weeks or even years after the initial occurrence.
