I would suggest a 3 month course of an aromatase inhibitor such as letrozole 2.5mg per day.

Thanks Sanjay, I'll consider this sugestion after understanding better its action.

Dear claudio

i consider a intersting option to treat endometriosis with letrozole in that patient with lupus,

but if its necessary you cant use progesterone,

you must to rejetc other cuases of chronic pelvic pain

as gynecologic vasculitis, interstitial cystitis, i know that you have this in mind.

Dear Jair

Thanks for your suggsetion. I'll consider it.

I am a scientist with rare autoimmune condition not that dissimilar to lupus. I manage my own condition under the guidance of my doctors as not much is know about my condition. I also went through difficult endometriosis surgery which dramatically improved pain but did not eliminate it. Based on my knowledge and experience, I agree with JAir and vasculitis would certainly be one thing to consider. It will not be welcomed from a doctor but based on my experience learning to live with the pain makes it more manageable.
