Hi, feeling balance problem regularly, my self daibetic but things are under control..fasting 102..PP: 164..and when sits on chair sometimes feels like I am going to fell in front of office desk. Left body pain is coming some time like left neck, left back, left leg are feeling with pain with some specific point or muscles..done MRI for mind and spine but not able to find any difficulty..don't understand it is due to annexity/stress or diabetic..or any nerves problem.
