Causes of Left Arm Numbness
What causes numbness in the left arm? The causes of this condition can include:
Fractures
There may be elbow, arm as well as fingers that have become fractured which cause the numbness of the hand. Hand and arm numbness because of fracture is normally accompanied with sharp pain in the area of the fracture.
Nerve Compression and Nerve Damage
At times the nerve that runs from the left arm to the central nervous system becomes compressed. This is one of the more common reasons for left arm numbness. This is due to the interference of blood circulation in the left arm as well as the pinching of the nerve. One of the main causes of nerve damage is diabetic neuropathy. Another cause of nerve damage is carpal tunnel syndrome which is caused by compressed nerves in the wrist and is one of the leading causes of injury in the work place from working on computers.
Ganglion Cysts
These are non-cancerous growths which develop on the hand but mostly on the wrists. These cysts can develop rapidly or gradually and can affect joint movements as well as cause numbness in the left arm. They can be removed by surgery.
Raynaud’s Disease
This syndrome can cause the fingers to become numb and is caused by the arteries in the arms becoming narrow thus causing the numbness. Many women suffer from this problem.
Stroke
Many cases of left arm numbness are caused by stroke. This is caused by blood supply to the brain being reduced or interrupted and depriving the brain of nutrients and oxygen.
