My sister and I both have endo. I also have a twin sister, who does not
have endo. I have been thinking about what was different about our
childhood that could have possibly lead to 2 of us getting endo, while
my twin sister remaining endo-free.
The 2 of us that have endo got perms as teenagers. Any chance that this
could be a potential cause? Sounds crazy, I am sure, but who really
knows.....
