RedactedNarrative: While wakeboarding Injured fell routinely with his left arm smacking the water hard. This caused his shoulder to dislocate causing him extreme pain. Injured told me his shoulder has been an ongoing issue for him, but nothing irregular happened when he fell.
  
  I became aware of the accident when it was reported to me in person. I met the vessel at the dock where Injured denied EMS response. I provided first aid treatment with an impromptu sling to stabilize Injured's left arm to alleviate some pain. A friend of Injured transported him to Logan Regional.
