I was finally diagnosed with endo as well at 16 with a laparascopy, after years of symptoms, and diagnosed with MI even earlier. They do exacerbate each other at times with the symptoms overlapping at times coloring my outlook, and more so the treatments affecting each other. It is hard sometimes to know which is which to help manage the symptoms; kind of a catch-22 scenario with treatment: helps one but aggravates the other condition or aggravates both, rarely helps both which is ideal to find and worth pursuing. It is frustrating and has been a very hard road to travel over the decades to manage them both. Thanks to finally finding good providers, this has been most helpful.
I do understand though how they can influence one another. I hope you find what works best for you to manage them. Hang in there.
