Delighted to have you back here @epspecially
One thing to note with surgery for endometriosis is that it removes the lesions but the body has to heal 20 or 30 years worth of inflammation and pain. This can take time and often extra input from diet, exercise, pelvic physiotherapist etc..
Have a look at Dr Iris Orbuch new book Beating Endo https://www.bookdepository.com/Beating-Endo-Dr-Iris-Kerin-Orbuch/9780008305529/?a_aid=EAIWEB for some tips.
Adenomyosis may be a possibility, and a hormonal suppression may help here but that depends on how you feel about that.
I was going to move this to a main thread but with the replies I’ll leave it here for now x
