Symptoms: Often there are no symptoms. In the first or primary stage of infection, may have a single sore or multiple sores on mouth, throat, genitals, or anus. In the second stage, may have a skin rash (often on the palms of the hands and the soles of the feet, but also on other body parts). The symptoms of syphilis will disappear with or without treatment, but without treatment the infection remains in the body and may cause organ damage.
