Endometriosis can be a pretty terrible condition to have.
If you have endometriosis, tissue from the uterine lining ends up in parts of the body it shouldn't be, causing serious pain, bleeding, inflammation, bloating, and other problems.

And that even with treatment, the symptoms may not go away entirely.
