I've never had it easy with periods. My 2nd period, I had such bad cramps that I dissociated into a "white out" (could only see white light, no shapes) and walked straight into a concrete wall. I also couldn't stop walking! I fell onto a concrete floor on my face, but was unhurt beyond bruising.
Falling and the pain brought me back and I was "fine." I was 12. I think it was a kind of out of body experience or dissociation, now, based on what I've read lately, due to the pain in my sexual organs triggering my brain back to pre-verbal trauma.
I had the ablation procedure done not because of anemia or pain. It was due to menses actually triggering my PTSD again like the past, causing me to miss days of work in a dissociative fog (not bad enough to walk into walls, so just dissociated.)
After the procedure, the pain and other symptoms are worse. So who knows. I don't want to live at the Dr's. This has been my whole life. It's the trauma. I've been checked so many times and they see nothing wrong. It could be body memories.
