All I can do is say go back to the hospital's A and E dept and refuse to leave until you see an orthopaedic specialist!! I had a similar thing happen when I broke my elbow. I made such a fuss and refused to leave and was in tears with the pain They actually did send for the surgeon because I was such a nuisance! It was a simple solution in my case they had put my arm in an unsuitable sling position and the specialist just put the sling on correctly.
You shouldn't be suffering like this.
I wish you well.
