Can I get compensation?

I'm working on boat, I have been injured during my duty, my supervisor sent me to help other company who was on board during the dry dock, while I was working I get injured and after few minutes I went to medical to report injury, doctor exam me and said 'That is nothing' 'Just put some ice on that and shuld be ok, our x rey on board doesn't work so I will make appointment for you...' When I was leaving medical facility I asked a doctor: 'Doctor so am I fit for duty now' and doctor said 'Yes, you are fit for duty' ,tomorrow I was on duty doing all regular things what I usually doing *lifting heavy things, pushing heavy props, pulling ropes ... and day after tomorrow they call me to drive me at medical facility off board to exam my injury and take a picture with x rey, doctor in that medical facility said after x rey and examing that I have a fracture and I'm not fit for duty at least 4 to 6 weeks, so after that report they send me home for medical sing off
