I'd go and get a doctor / physiotherapist / geisha to look at your neck, too. It might pass by without any treatment, but it also might only require a little cold / heat / pressure treatment, too.
Did she do that because of the treatment for her illness? Ive seen people do that before for that reason. Not the eyebrows mind you but eh, she was showing you a thing or two.
She had wanted to shave her head for a while, and finally decided to do it. Its really putting a lot of strain on a relationship that was already strained. Every time we talk she brings up her hair, which eventually leads to me mentioning how much I hate it, which pisses her off and I get in trouble.

I've been over it for weeks, but she keeps bringing it up.
I had to create a list of "banned subjects" with a particularly truculent partner. Basically this is a list of topics that are agreed by both parties to be unimprovable with further conversation, and serve only as mechanisms for escalating a discussion into an argument. Just agree beforehand who was to blame, if that is what is required, then agree that they will not be spoken of again (at all preferably, but at least not during a discussion about other things, and definitely not during an argument).
It allows you to say "Wait a minute, we agreed that we wouldn't talk about that anymore. Yes, it was my fault, and No, neither of us can do anything about it now. Let's talk about what we really want to talk about, instead."
Good luck.
