My question is what is the chance of false test or my treatment failing if I was infected? Here is why. Recently my partner was having back, stomach, and pain in the private area. My partner was diagnosed by the doctor ( which I wont share at this time unless you need more information); however, my concern is because of the pain in the private area . The only symptoms of PID this person has is pain in the abdomen and private area but it also goes along with the diagnosis. Could this be PID because of my unexposed oral event from a few months ago? I know it sounds crazy, but when my partners pain started, I felt like maybe my mistake was coming back to haunt me. 

Your partner's symptoms are a coincidence. The only STD from oral sex that could cause PID is gonorrhea. Other STDs from oral sex, such as nongonococcal urethritis (NGU), are not known to be caused by bacteria that can cause PID. The is a very small statistical chance that any one test for gonorrhea could be falsely negative; that you could have acquired gonorrhea without symptoms; or that the treatments you had would not have cured it. But the odds that all of those things happening -- including 2 negative tests -- is statistically too low to be realistic. Zero chance for all practical purposes. Therefore, you can be 100% confident your partner's symptoms are not due to gonorrhea from your oral sex exposure. In other words, I agree exactly with Dr. Hook's evaluation and advice.

As for your partner's symptoms, there is too little detail for me to say very much. "Private area" is nonspecific; you refer to abdominal pain, but is that all? Does she have any sort of genital pain (vaginal? labia?). Pelvic (low abdominal) pain is a common symptom of PID, but also of a large number of other disorders:  endometriosis, appendicitis, ovarian cyst, diverticulitis, and more; as well as mild, unimportant intestinal infections. PID is usually accompanied by other symptoms as well, such as abnormal vaginal dischrge. The important thing is that she be professionally examined to learn the cause of her pain. If she does so, you need not mention your other exposure or treatment. There is no realistic chance it has anything to do with your partner's problem.

I hope that helps. Let me know if you have other information about your partner's symptoms or if there is anything that isn't clear.

So all is well. Support your wife as needed, if her symptoms continue. But don't worry about the oral sex event. It has nothing to do with her symptoms.
