Diagnosis

The doctor will ask about your symptoms and past health. A physical exam will be done. Tests for cause of infection may be done with:

  • A swab of the penis, cervix, throat, or rectum
  • Urine tests

Treatment

Antibiotics are used to treat the infection. Sexual partners should also be treated or the infection will continue to recur.

The risk of this problem may be lowered by:

  • Abstaining from oral, anal, or genital sex.
  • Limiting sex to 1 partner
  • Using latex condoms during sex
