My husband suffers from severe upper arm pain in both arms that radiates to his hands. he also has numbness in his fingers. doctors cant figure out whats going on. its interfering with his life. please help us. no one else seems able to?

Nerve impingement or bilateral neuritis are possible causes. Has a neurologist evaluated him? An EMG seems indicated if not already performed. An MRI of neck vertebrae may shed light. If already seen by a neurologist, I recommend consulting another at a department of neurology at a university hospital near you. I am confident that a definitive diagnosis will be obtained with a proper testing.
