Lower back pain during my period

Hi ladies, how are you?

I’ve had menstrual cramps my whole life during my period.
When my TMS symptoms started (lower back pain was the first), every time I had my period, besides the cramps, I would also have an increase in the lower-back sensations.

I’ve been on continuous birth control pills for six years to avoid getting my period. Almost every month I have some breakthrough bleeding — not much cramping, but a lot of lower-back pain, which hardly improves even with anti-inflammatories.

I’ve done imaging tests to rule out endometriosis (I have some other symptoms as well, like pain during sexual intercourse — but who doesn’t, with chronic pain?). The imaging showed nothing. People on the internet — even doctors — say that endometriosis can be difficult to diagnose through imaging tests.

I’ve tried the TMS approach for my lower-back pain during my menstrual bleeding, but I haven’t seen many results.
I keep going back and forth, wondering if it’s all TMS or if there’s some structural issue, like endometriosis.
What keeps me unsure is that outside my period, certain triggers cause my lower-back pain, and I have a lot of evidence pointing to TMS. But during my bleeding, the pain is pretty constant.

Any thoughts about this?
I’d love to hear from the ladies here and know if anyone has gone through something similar.

Thanks.

 

If that imaging didn't also rule out fibroids, then I'd do that before putting these symptoms down to mind/body/TMS. I suffered lower back pain during my periods and just put up with it. It wasn't until after my menopause that I had an ultrasound scan (for something else) and the sonographer said just in passing, "I see you have fibroids; I bet you had a lot of painful periods with those!". Up until then, I'd had no idea that I had fibroids and that they were more than likely responsible for my pain.
