Adenomyosis. Thank you for this clear explanation!!! My 1st biopsied lap @age 17 dr said the muscle tissue was hardening and he didn't know why!! 2 surgeries and over a decade later my uterus was 3Xs normal size and they finally believed me about the pain. I should have had help or disability!!! Hard not to get angry about something so tangible they tried to make me think was in my head!
