<human>: I have pain in shoulder that radiates into right shoulder blade, armpit, down my arm into the palm of my hand. Previously had 2 cortizone injections over last 1.5 yrs. for rotator cuff inflammation.  Never pain in my armpit, forearm or hand though until now. Thanks!
<bot>: Hi there. Firstly rotator cuff pain is more localized to the region around the shoulder. What you might be having here would probably be a nerve compression. This can happen at the level of your spinal cord, vertebrae to the many nerves supplying your hand. So if a patient presented to me that's what I would be ruling out. Especially since you mentioned that your pain is radiating, that is why I would be suspecting this all the more. You need a checkup of your right upper limb muscles to see if there is any associated weakness or any sensory loss, and a spine evaluation as well. Its also more likely if you had any history of doing any strenuous activity or trauma in the recent past. So I would suggest that you get yourself evaluated for the same.
