I know all about pain too, and the fact your husband says that infuriates me, he does not have any idea what he is talking about, he needs to be educated and fast, Endo is a very painful condition , and I really feel for you, try joining a support group where you can talk with other women and get ongoing support that you need and get that hubby along if possible, if only it was all in your mind, then you could fix it.

I am sorry you have to endure this, it is not pleasant, all I can do is send you my hugs and not very adequate advice. Take care.
