Symptoms of a sexually transmitted infection (STI)

Sexually transmitted infections (STIs) can cause many different symptoms. They may include:

  • Abnormal discharge from the vagina, penis, or anus. This may get worse over a period of several days to 2 weeks.
  • Pain, burning, or itching while you urinate that lasts for longer than 24 hours.
  • Cloudy urine.
  • Fever.
  • Pain during sexual intercourse.
  • Pain or a feeling of heaviness in the pelvis or lower belly.
  • Itching, tingling, burning, or pain in the genitals.
  • Sores, lumps, blisters, rashes, or warts on or around the genitals.
  • Vaginal spotting or bleeding after sexual intercourse.
  • Crusting at the tip of the penis.
  • Other symptoms of an infection, such as a rash, fatigue or lack of energy, or swollen glands (lymph nodes).

But STIs don't always cause symptoms. And sometimes STI symptoms will go away or change quickly. This doesn't mean that the STI has gone away. Getting tested is important if you think you may have an STI or have symptoms.
