My Father is diabetic since 4 year And now he is having some kind of pain on his right shoulder and neck at same side. This pain start from neck. And shoulder and goes till the single finger. When it started it started from left shoulder but left shoulder is okay now it pain less. But whole thing is moved to right shoulder neck and hand. We have visited general physician and he have given some pain killer but that is of no use in long run. He sugar is low since two month but as per the report ecg there were some synus something was there. Can anyone plesse help me i dint know whom to visit and where to visit. Thanks in advance
