What does it mean when you have a lower back pain with lower abdominal pain with a clear white discharge?

This question requires a medical assessment of the person suffering these problems. That can be obtained from a Physician or perhaps a Physician's Assistant or Nurse. Anyone needing an answer to a question like this who does not have ready access to their own doctor should seek advice at a clinic or hospital emergency room. Never put any trust in medical answers to specific medical questions in a forum like this.
