Arm numbness
Informed by recognized medical guidance
Overview
Arm numbness is a loss of feeling or a 'pins and needles' sensation in your arm. It can affect one arm or both, and may come with weakness, tingling, or a burning feeling. Often it is temporary and harmless, but sometimes it can be a sign of a more serious condition, such as a problem with the nerves, spine, or blood flow.
Key facts
- Arm numbness is common and often goes away on its own.
- It can be caused by pressure on a nerve from sleeping in a bad position or from repetitive activities.
- Sudden numbness on one side of the body – especially with face drooping or trouble speaking – is a medical emergency (stroke).
Yes, arm numbness is very common. Most people experience it at some point, usually due to temporary pressure on a nerve.
Arm numbness can affect people of any age, but it is more common in adults who do repetitive arm or hand movements (like using a computer mouse or playing an instrument), people with diabetes, older adults with arthritis, and those who have had a neck injury.
