Hard Nipples, but low E?

I have been upping my anastrozole due to being told that nipples getting hard is a symptom of gyno. In fact, was getting a bit gyno-paranoid even though I was just on 300mg enth. Ended up ordering Letro, had blood drawn right before starting the Letro while I was still on 1mg anastrozole/day.

Anyway, the blood came back and my e was at 10, so no gyno, but still have the symptom. I even had en endocrinologist check me for gyno and had a clean bill of health.

Has anyone else had this symptom but not related to gyno?

So your symptom is that your nipples are hard. As in how they get when its cold outside?

Yeah, pretty much - though without the external stimulus. Seems pretty random, can last for a minute or two, or for somewhat longer, though I don't think more than 15-20 minutes at a spell.
