Can endometriosis cause pain in the lower back which extends to the bowels and bladder?

Hello doctor,

I am 42 years old and had permanent birth control implants inserted 8 years ago. After the insertion, I began experiencing persistent pelvic pain. After this, cysts were discovered and I was prescribed birth control pills in an attempt to regulate my symptoms. But, the birth control pills exacerbated my menstrual cycles and PMS symptoms rather than reducing them. Two years back, I underwent a laparoscopy procedure during which endometriosis and bladder flap adhesions were identified and surgically removed. Following a period of relief lasting 4-6 months, all my previous pain and symptoms resurfaced.

Last year, I opted for an IUD insertion with the hope that it would cease my periods. But, for 3-4 months, I experienced heavy bleeding, which eventually subsided. Yet, I continued to have brown discharge around ovulation and the persisting symptoms. Presently, I am grappling with sensations of pressure, bloating, and pain in my ovaries, lower back, and pelvis, including nerve-like pain. The pain extends to my bowels and bladder. Over the past 1-2 years, these feelings and symptoms have arisen, leading me to consider the possibility of entering a premenopausal phase. Throughout this ordeal, I have been diagnosed with compound cysts, PCOS, and endometriosis. My concern is that there may be a new issue, a recurrence of a previous condition, or a previously overlooked condition that is now affecting other organs.

Despite my efforts spanning 8 years to uncover the root cause of my distress, I remain without relief. Please help.

Thank you.
