Well basically I have injured my right arm There is

Patient: Well basically I have injured my right arm. There is an aching feeling through my whole arm and hand, when I try to straighten or bend my arm there is a strong sharp pain that shoots through my whole arm. The pain started when my arm got trapped in the frame of my bunk bed while sleeping, because I was still half asleep I pulled my arm out the bed frame without realising how fast I pulled it out and then felt a very strong pain shoot through my arm. the centre of my arm hurts the most when trying to move my arm. I don’t know whats wrong

Doctor:
