Dx pid in er. had us and pap. pap normal, negative for std/sti. confused about other possible causes, or was this incorrect dx? no hx endometriosis

Possibly Wrong DX: I find that ERs over diagnose women who present with pelvic pain and/or vaginal discharge with PID. It would help to have more information, including symptoms you had. I assume they Rxd antibiotics , and your US was normal. They likely tested you for GC/Chlamydia, which are the most common causes of PID, but not the only pathogens that can cause it. If no better see gyn specialist. Take Care.
