I reported a dr to my state medical board years ago. He told me that I couldn't have a certain antibiotic with my meds at the time but when the antibiotic he prescribed instead didn't work he prescribed the one he said was unsafe. Repeated 3 times. I already was uncomfortable with him because he treated me like I was stupid b/c of the bipolar and he pretty much told me I was lying when I said I wasn't a nursing aide. I also had a herpes virus breakout on my mouth that was really deep and severe and he refused to treat it, even though I have had trouble fighting off herpes viruses in the past (I reached in a mouth of someone who was choking and caught herpes on my thumb which seems to have made me more sensitive). My pdoc finally wrote the order for the herpes treatment I needed.

But anyway, the medical board had me sign some forms and then they investigated him. It took about a year and he was found ok but at least it put some pressure on him.

I don't think that your mom will be allowed to file a complaint about you though. I think when you are an adult you have to do it yourself. But I 100% think you need to do it, both to protect others from his "care" and to help you recover from it.
