Injured My Hand Two Weeks Ago By Larg Dog By

Injured my hand two weeks ago by larg dog by the leash that was wrapped around my hand. Dog suddenly ran and once the leash slack was gone my hand took the impact.

Since I have sharp pain between my fouth finger and and my fith finger( not far below my hands knuckle). Went to urgent care they took x-rays and said they found a fracture on #4 (on the neck bone)and sprinted it. Since the treatment swelling has dramatically increased as well as the pain.

Had further x-rays taken at another facility ( hospital) and they said they found no fractures. Who do I believe and what do I do ?
