How do I have PID?

Sara

I have 1 partner my husband. I was tested and treated with my husband for chlamydia like 2 years ago. I have got 3 pap smears done and all of a sudden the er does the finger examination and diagnoses me with pid because it was hurting when he put his fingers all the way up there. My blood work I have gotten a few weeks ago doesn't show infection or anything. I don't get why all of a sudden I apparently have PID.

So now what my husband has to get seen for PID too?
