Sexually transmitted disease (STD) symptoms - Mayo Clinic
Some of the most common symptoms are described below. Changes in urination: An STD can be indicated by pain or a burning sensation during urination, the need to pee more frequently, or the presence of blood in the urine. Thick, white discharge can be a sign of a yeast infection. When discharge is yellow or green, it might indicate gonorrhea or trichomoniasis.
Most people with HSV never know they have it, because they have no signs or symptoms or the signs and symptoms are so mild they go unnoticed. When signs and symptoms are noticeable, the first episode is generally the worst. Some people never have a second episode. Others, however, can have recurrent episodes for decades.
