In total are these symptoms related? No diagnosis as of yet.
Hi, Phonic nerve palsy can cause both these, shoulder paralysis and diaphragm pathologies. Phoenix nerve originates from cervical vertebra in neck. And it supplies shoulder joint and diaphragm. So any pathology of a cervical vertebra which is causing Phoenix nerve damage can cause neck pain, shoulder paralysis and diaphragm pathologies.  So in my opinion, you should definitely get done MRI of cervical spine to identify Phoenix nerve injury.  Hope I have answered your query. Let me know if I can assist you further.
