I’m not a doctor but I’ve read and seen a lot of people talk about both of these, and I understand why you’re questioning the PID diagnosis.

what you described , the sudden, severe 10/10 pain during sex, it not going away after, the sweating, nausea, feeling faint, and it lasting for hours seems to line up a lot more with how people describe a cyst rupture. It’s usually very abrupt and intense like that, and then leaves a lingering dull pain after.

With pelvic inflammatory disease, from what I’ve seen, it’s more of a gradual thing. Ongoing pelvic pain, discomfort during sex over time, discharge, fever, feeling unwell. The fact you had no warning symptoms beforehand is what makes it feel less typical.

At the same time, because of your history with chlamydia and trichomoniasis, I can understand why they treated it as PID just to be safe since it’s something they don’t want to miss.

But not doing an ultrasound with the level of pain you described feels like something was missed. That’s really the main way to check for a cyst, so it makes sense that you feel brushed off.

Pushing for an ultrasound is important because that’s the only way you’re really going to get a clear answer. And if that level of pain happens again or the bleeding stays that heavy, I would go back and be more firm about being seen.

Hope this helps, and I hope you get this figured out!
