The most common symptoms of PID include:

• vaginal discharge with abnormal color, consistency or odor
• abdominal pain either localized or generalized
• fever (not always present)
  • may range from transient to constant
  • low grade to high

Other nonspecific symptoms that may be seen with PID include:

• chills
• irregular menstrual bleeding or spotting
• increased menstrual cramping
• menstruation, absent
• increased pain during ovulation
• sexual intercourse, painful
• bleeding after intercourse
• low back pain
• fatigue
• lack of appetite
• nausea, with or without vomiting
• frequent urination
• pain with urination
