How nice it would be if there were always a simple and clear connection where one thing leads directly to another every time (ie low blood calcium=arthralgia). There are just too many factors (medications, genetics, lifestyle, comorbitities, etc) that can cause issues.
I have a pretty high tolerance for pain, but this was pretty bad. If it happens again, and it's possible to identify a direct cause and fix it, I'll be beyond happy. Evenity is otherwise working well for me, so I'd hate to have to stop the treatment.
