Hi all, I had intracranial hypertension due to low progesterone/estrogen dominance....though my estrogen levels are not high, just higher than progesterone which creates migraine and high pressure in the head. This is all very intimately connected with low zinc levels which causes copper retention copper is very inflammatory and a brain stimulant which causes severe anxiety, cycling thoughts etc. Mirena and other birth control pills cause this zinc/copper imbalance as well by shutting off out natural progesterone....you will notice if you chart your cycle that as estrogen and copper rise your symptoms get much worse, like during ovulation. Have any of you tried taking natural sublingual pregnenalone to help your body make progesterone? Also low copper diet and high doses of zinc help too. Best of luck to you all it took me 5 long years of research to figure this out and find my way back to better health
