All pulmonary tests show no real change, except for SNIFF which shows a
degradation. Phrenic nerve conduction tests also show a worsening. Cannot find a root cause for any of this, and my Drs. don't have any ideas about a tie with right shoulder pain. I have had every test imaginable, and have been on a BiPAP machine to allow me to sleep lying down. Any ideas ? I'm 49 yo, white male. Thanks! - Joe from upstate NY.
