<s>[INST] I fell down a flight of concrete steps with metal nosing. I landed on my right lower back with my right arm extended to catch the fall, but continued slipping down each time hitting a step while my arm was extended. I felt as though my arm was ripped off at the right shoulder. The doctor took x-rays and found no broken bones. He believe that I tore my bicep tendon and bruised my back. I am beginning to get range of motion back in my shoulder/arm, but it is still not healed (the accident was three days ago). My back is hurting quite a bit. The doctor prescribed PT for two weeks with a follow-up appt. I wonder why he didn t do a catscan or mri to determine any soft tissue damage? Should I be concerned of other possible injuries? [/INST] Hello,Bony injury is unlikely and most probably you might have injured muscle or tendon like biceps or rotator cuff. If you are experiencing pain or difficulty in rising the arms it is better to go for an MRI scan of the shoulder.Hope I have answered your query. Let me know if I can assist you further.
