This is long shot but do you find the progesterone makes it worse? The reason I ask is that in October, I started on bio-identical hormones. First with an estrodial patch for two weeks and then I was to start Prometruim 100 mg at night (oral bio-identical progesterone).

In about four days after starting it, any joint issues I had got worse and my feet would ache. I don't have PN but I do have some joint/tendon/muscle issues and found oral progesterone aggravated it. Once I stopped, I returned to my normal aches and pains.

I switched to a topical bio-identical and that does not have the same effect on me.
