Non-cancerous growths like ganglion cysts can press on nearby nerves, leading to numbness, discomfort, or limited hand movement.

Infections

Certain infections, including shingles and Lyme disease, can directly affect nerve health and lead to tingling in the hands and other parts of the body.

When Should You See a Doctor?

While the occasional tingle isn’t usually a big deal, some symptoms warrant immediate medical attention. Contact a healthcare provider if you notice:

• Sudden weakness or paralysis
• Slurred speech or confusion
• Dizziness or trouble walking
• Numbness spreading to other parts of the body
• Tingling that doesn’t go away or worsens

Final Thoughts

Hand numbness or tingling can come from something as simple as sleeping the wrong way—or something much more serious. If symptoms are persistent, unusual, or worsening, don’t ignore them. A doctor can help diagnose the cause with blood tests, nerve studies, or imaging, and recommend the right treatment plan.

Your body is always sending signals—it’s up to you to listen.
