Hand & Arm Complications


Chronically elevated blood sugars can damage the upper extremities.

Hand complications include:

  • Neuropathy
  • Carpal tunnel
  • Dupuytren's contracture
  • Trigger finger

Hand and arm (upper extremity) complications include nerve damage and tissue damage from chronically elevated blood sugars.

Hand complications


Symptoms are tingling, pain and/or numbness in the fingers and hands. Less commonly, there can be muscle weakness and loss.

Carpal tunnel or ulnar tunnel nerve entrapment syndrome:

Nerves can get pinched by soft tissue buildup in the nerve tunnels in the wrist (carpal tunnel) and elbow (ulnar tunnel). This pressure on the nerves leads to pain, tingling, numbness and sometimes even muscle wasting.

Dupuytren’s contracture

This is a shortening of tendons in the palm of the hand that bends the fingers and keeps them from being straightened.

Trigger finger

In this condition, a nodule on the tendon gets caught and keeps the finger from fully straightening.

Shoulder complications

Frozen shoulder

Buildup of connective tissue causes adhesions in the shoulder joint space. This restricts arm movement and can be very painful.
