As for my doctor, I don't know if she's an endo but she's in general practice. She's also known as being one of the top docs in my area for HRT, at the top of everyone's recommendation lists. Her practice takes about eight weeks to get into and appointments are booked months in advance. So even if she's not an endo, I like to think she knows her stuff.
Then again, my case seems to be anything but ordinary now.

I'm just not having an easy time with HRT at all, but it's typical for my body. I counteract every treatment any doctor had ever given me my entire life, to the point that I've always needed the strongest doses of the strongest medications to get through anything. I think my HRT treatment is probably way too conservative for how my body has historically reacted to meds.
Thankfully I haven't had any side effects from the depo except for the crushing moods. For a short while, spiro seemed to decrease my already-sparse body hair, and that stopped with depo but no additional body hair has come up. My sex drive on spiro was out of control and depo killed it. As for hearing, I wouldn't notice anything like that because that's my reality anyway: unable to hear people very well in crowds. I had hearing loss from ear infections as an infant so it's been like that my whole life.
