Arm and Hand Numbness and Tingling Explained
Princeton Spine & Joint Center・9 minutes read
Numbness and tingling in the arm and hand can indicate various nerve entrapment syndromes, such as carpal tunnel, cubital tunnel, or radial tunnel syndrome, potentially originating from the neck as well. Double crush syndrome, where a nerve is compressed at two points, can complicate diagnosis and treatment, highlighting the importance of comprehensive evaluation with electrodiagnostic studies and MRI scans.
Insights
- Numbness or tingling in arm/hand could signal nerve issues; wrist, palm, finger symptoms may point to carpal tunnel; neck pain into arm/hand may indicate pinched nerve at neck level.
- Specific fingers affected can suggest different nerve entrapments; radial nerve issues at back of hand might link to neck problems; double crush syndrome warns of misdiagnosis risks, necessitating thorough evaluation like electrodiagnostic studies and MRI scans.

Arm and hand numbness: nerve involvement summary.
- Numbness and tingling in the arm and hand indicate nerve involvement or irritation.
- Symptoms in the wrist, palm, and specific fingers suggest carpal tunnel syndrome, especially if worsened by morning or computer use.
- Neck pain radiating into the arm and hand indicates a likely pinched nerve in the neck, possibly at the c6, c7, or c5 spinal level.
- Symptoms in the pinky and fourth finger suggest ulnar nerve entrapment at the wrist or elbow, known as cubital tunnel syndrome.
- Involvement of the radial nerve on the back of the hand may indicate radial tunnel syndrome, potentially linked to neck issues.
- Double crush syndrome, involving two compressions of the same nerve chain, can lead to misdiagnosis and inadequate treatment, emphasizing the need for thorough evaluation, including electrodiagnostic studies and MRI scans.
