As I have posted before, my body no longer tolerates natural progesterone so I have been cutting back. I just ovulated and to my despair, my endometriosis pain is back and I have not been bothered by it in years. I assume it is because I am getting less progesterone. I initially went on the progest to deal with the endo problem which it obviously has been keeping at bay.
I am still using the same amount of estriol cream (1/16th tsp a day) but only 1/16th 3% progest at night and a tiny bit in the morning.
Has the endo returned because I am using less progesterone or because the estriol is not as balanced by the progesterone?
Any ideas?

Endometrosis can be fueled by hormones, particularly estrogen. However, the amount your are using is so small and estriol is the weakest estrogen of the three. Are you perimenopausal?

Hi Gevalia,
I am 40 years old. Am using a bit of estriol for vaginal dryness and dry eyes (doc thought it may help). I'm so frustrated with my body. I've had a lifetime of menstrual pain, endo, ovarian cysts etc etc. The progest seemed to really help keep the endo in check but can't use much any more as it gives me an adrenaline rush.
I cut back a little on the estriol today in case it was worsening the endo and I am now having hot flushes! Aghhh!

I was 43 when I had my hysterectomy due to endometrosis so I know what you mean about the cysts, adhesions, endo pain, etc. I was lucky to make it that long with my ovaries intact. Anyway, the reason I ask is because after my hysterectomy I used nothing for years. Not because I wanted to go without, but because the doctor wanted to give me only Premarin, which I won't take. So, it seems the endometrosis remaining after my hysterectomy died out without the hormonal stimulation. I now use an estrogen patch & otc progesterone cream (3%) with no problem or reoccurence. Guess I don't have any answers for you since you can't tolerate progesterone. What does your doctor say?
