I am so sorry you are dealing with pain and possibly endometriosis! My
goes out to you!
Having a laparoscopy to see what is going on and possibly cleaning up as much endometriosis as possible could be helpful for you. Keep in mind, that if your surgeon does not have the skills to remove all the endometriosis he finds, you could continue to have pain and issues from any remaining endometriosis. I continued to have issues as my GYN could not remove the endo from my bowel walls. Years later, I had to travel to an endometriosis specialist
who was able to remove that endo and all the other endo and adhesions he found. I had an adhesion from my vaginal cuff to my bowel that was a big part of my symptoms! It has been two years since that surgery and I am doing well! (And yes, I still have both of my ovaries because that is what is best for me.)
The stats for endometriosis recurrence somewhat depend on who shares them! Endometriosis specialists tend to have lower recurrence rates among their patients than a general GYN will have. For one, the more of the same type of surgeries you do, the greater skill you can have. A general GYN isn't generally going to be treating as many women with endo as a specialist. Some women have had great success having surgery with gynecological oncologist for endometriosis because those types of doctors have exceptional skills when it comes to delicately removing stuff that does not belong in the body!
Was endometriosis ever found during any of your prior surgeries? Is the surgeon you are seeing now the same one who has done your prior surgeries? Endometriosis and adenomyosis do not always go hand in hand. There are many of us here on the site with one or the other condition, but not both. So, while it is possible for endo to rear its head sometime after a hysterectomy, there might also be some other issues going on.
I wish you all the very best for your upcoming procedure and hope it offers you the pain relief you need!
