Sexually transmitted diseases list and symptoms encompass a range of infections, each with its own set of symptoms. Chlamydia, for example, may cause abnormal vaginal discharge, painful urination, lower abdominal pain, pain during sexual intercourse, and bleeding between periods in women, while men may experience clear or cloudy discharge from the penis, pain, or burning during urination, and testicular pain or swelling. Gonorrhea, on the other hand, can lead to increased vaginal discharge, painful urination, vaginal bleeding between periods, abdominal or pelvic pain, pain during sexual intercourse in women, and similar symptoms such as discharge and pain during urination in men. It's important to note that these are just a few examples, as there are many other STDs with their own unique set of symptoms. If you suspect you have an STD, it's crucial to seek medical attention for proper diagnosis and treatment.
