It’s really hard to know without seeing the area, so I think it’s important to see your doctor and get tested, which is pretty easy. Syphilis is typically transmitted by directly touching (usually when having sex) an open sore on someone else. About two to three weeks after contact with the open sore, a new sore develops which looks like a bump, but then turns into a painless sore with raised edges. Usually the lymph nodes around the area get swollen as well. If this is happening to you, be sure to see your doctor as ignoring syphilis can lead to big health problems. If caught in this early stage it is usually very easy to treat with antibiotics.
