Do I have AIDS or plum blossoms in my groin?

You can't be sure it's syphilis just by looking at these rashes.

Syphilis symptoms mostly occur in reproductive organs, and men are in the coronary sulcus, vulva trunk and skin foreskin. Women are in the labia majora or cervix. Due to different sexual intercourse methods, chancre can also appear in the mouth, face, anus, rectum and even limbs. It starts with papules and quickly breaks into small red ulcers, about 1-2cm in shape, with a small amount of serous secretions and a large number of treponema pallidum, which is highly contagious. Sometimes it may be accompanied by swollen inguinal lymph nodes, but there is no redness, pain, fever or suppuration. You can do a syphilis serum test to determine whether you have syphilis.
