Hi I fell down stairs last night and had excruciating pain in my right shoulder area just below scapula. I have a stabbing pain when breathing in deeply but not as bad as when I cough. I am able to move both arms around freely and whilst sitting down in an upright position all syptoms ease. Been taking Neurofen express every four hours. I also got hematoma on my right hip with friction burn from the stair carpet. I can raise my arms above my head and there is no problem. Would you suggest it is a muscular injury as opposed to ribs or lungs?
