4. Electrolyte Imbalances
Minerals like calcium, potassium, and sodium help regulate nerve signals. When these are out of balance — due to dehydration, certain medications, or health conditions — tingling or numbness can occur.
5. Diabetes and Nerve Damage
High blood sugar levels can damage nerves over time, leading to diabetic neuropathy. Tingling, numbness, or burning pain in the hands and feet are common symptoms of this complication.
6. Neck and Spine Issues
Herniated discs or age-related spinal changes can put pressure on nerves in the neck. Since these nerves extend down into the arms and hands, the result may be tingling, numbness, or radiating pain.
7. Autoimmune Conditions
Diseases like rheumatoid arthritis or Guillain-Barré syndrome may cause inflammation or damage to nerves, sometimes leading to tingling sensations. These conditions are often accompanied by other symptoms, such as joint pain or muscle weakness.
8. Circulation Problems
Poor blood flow can affect the hands, causing tingling or numbness. Conditions like Raynaud’s phenomenon (triggered by cold or stress) or narrowed arteries (atherosclerosis) can reduce circulation and impact nerve health.
9. Nerve Compression by Growths
Ganglion cysts or other growths near joints and tendons can press on nerves, leading to numbness, tingling, or discomfort in the hand or wrist.
10. Infections Affecting Nerves
Some infections directly impact nerve function. Shingles and Lyme disease are two examples that can cause tingling sensations in the hands alongside other symptoms.
When to See a Doctor
Occasional tingling in your hands is usually harmless. But seek medical attention right away if symptoms are:
- Persistent or worsening
- Accompanied by weakness or paralysis
- Linked to slurred speech, confusion, or dizziness
- Spreading to other areas of the body
These could be signs of a more serious condition requiring urgent care.
