I participate in Roller Derby. Whilst skating I fell forward and injured my arm thinking id sprained it or similar. Initially I was unable to move it but as days have gone by its got better. Now my upper arm aches constantly . Could it be broken. There is no bruising .
Hello. A constant ache in the area can be due to a muscle tear or a minor fracture also. You need to get an MRI scan done to find out the extent of injury.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
