Genital sores are a common symptom of sexually transmitted infections or diseases. Genital sores can be painful or painless, and red or flesh colored in appearance. Other symptoms include unusual discharge, a burning sensation during urination, or itching. Genital herpes and syphilis are the most common STD/STIs that cause genital sores. Herpes typically causes clusters of painful red blisters that may be itchy. Syphilis may be associated with a solitary, painless, red sore on the genitals that may be followed by a rash on the hands and feet. If there is a wound on your genitals that does not heal within a few weeks, you should always visit with your doctor for a checkup. In rare cases, it may be a sign of some form of cancer.
