Genital sores, or lesions, can last anywhere from a few days to several weeks. It depends on the cause of the sore, as well as individual factors, such as the person's overall health and how quickly they respond to treatment.
Herpes sores, for example, can last for up to three weeks and may recur periodically. Genital warts, caused by the human papillomavirus (HPV), can last for weeks or months, depending on the severity of the infection and the person's immune system.
Other causes of genital sores, such as syphilis, chancroid, and lymphogranuloma venereum, may take longer to heal. In these cases, sores may last for several weeks and may require treatment with antibiotics.
In some cases, the sores may not completely heal, leaving residual scarring or discoloration. This is especially true for recurrent infections, such as herpes.
It is important to see a doctor if you notice any genital sores or lesions. A doctor can diagnose the cause and provide the appropriate treatment to help the sores heal quickly and reduce the risk of complications. They can also provide information on how to reduce your risk of re-infection.
