I was wearing a safty harness, as we were heading for a ladder to the roof, and a toolbelt. When I fell the metal D-Ring from the
harness drove
in between my shoulder blades, causing my ribs/sternum to let out a honeycomb like crunch, the belt buckle drove into my lower back and the harness rings hit my mid back. When my head hit the ground the hard hat harness broke.
When I was taken to the hospital it was misdiagnosed as a pulled muscle based on clean X-rays, no head scan.
