Yes, I had that pain with periods and bowel movements for years and years. I also had long heavy periods and lots of cramping. The dr told me to take 800 mg of ibuprofen every six hours starting a day or 2 before my period started. Since my periods were also irregular I started once I felt any sort of difference that might indicate it was going to start. I got pretty good at estimating when and it did often help if I started before the pain was noticeable.
Endometrial tissue becomes inflamed during our menses. Ibuprofen is an anti-inflamatory and also prosteglandin ?. I don't remember for sure about the name of the part that influences production of hormones? affect of ibuprofen or if other anti-inflamatories have the same affect.
This was back in the early 70's. I don't know if they even knew about endometriosis then. Because the pain got to be excruciating causing me to miss several days of work the ob/gyn reluctantly decided to do ezploratory surgery. I had large amounts of endometrium adhering to my intestines. He scraped out as much as he could and I felt much better for a few months. Eventually I was having severe pain again and was told that the endometrium continues to grow. Sigh! More years of pain. Then an ultra ssound showed that I had unterine tumors and I chose a hysterectomy. After surgery they told me that quite a bit of my pain was caused by adhesions from previous surgeries.
By that time I was in my mid 40's. Relief at last not only from the pain but from a generally pervasive attitude of the early doctors that said, in effect, that it was all in my head.
:( :) I knew it wasn't but I continued to feel angry after the drs stopped saying that.
Medicine knows much more about endometriosis now than they did then. I've heard that there are more effective ways of treating now. There is nothing to be done for adhesions. I still have some pain from those if I run for very long or jump.
