My back hurts

I’m feeling so dejected from experiencing almost constant back pain in peri. Seeing a PT but no relief. It’s my lower back, over my sacrum and kind of wrapping around my hip bone. PT did all the tests - it’s not SI joint, nothing obvious. I am a normal weight and exercise regularly. I’m on all the HRT. Nothing. No improvements. I finally requested some imaging and I’m hoping it gives me a path forward. Anyone else experience this, any advice? I think the joint laxity is my biggest issue - like the pieces just don’t fit together anymore. I’m tired. I hurt. 😞
