My right humerus is the worst one by far, because it had a bone cyst that wasn’t discovered until I broke the bloody thing, which required surgery to fix, but not until six months of healing of the break. They found a second bone cyst on the other side of it when they were doing the surgery, which they had missed up until that point because they had only taken x-rays from one angle. This started my lifelong suspicion that a lot of doctors are actual idiots.
Fun fact: the genetic disorder that caused this either affects one bone, all of the long bones, or nearly all of your bones. It won’t be affecting all of my bones because that would cause some issues that would be apparent by now, but they’ve never x-rayed any of my other long bones to check for cysts, so they could all be accidents waiting to happen.
Best: dunno. Got quite broad shoulders?
