Reasons You Could Have Numbness or Tingling Sensations in Your Hands

What Causes Tingling or Numbness in the Hands?

Tingling or numbness in the hands can stem from a variety of causes, both minor and serious. One common reason is sleeping in an awkward position,

which can temporarily compress nerves. Repetitive actions like typing may also cause irritation, especially in conditions like carpal tunnel syndrome.

Vitamin B12 deficiency can lead to nerve issues, causing tingling in the hands and feet. Electrolyte imbalances may also disrupt nerve signals,

producing similar symptoms. Diabetes is a major cause—particularly diabetic neuropathy, which results from long-term nerve damage.

Spinal problems, such as herniated discs or spinal stenosis, can compress nerves and trigger numbness in the hands. Autoimmune diseases like multiple

sclerosis may also interfere with nerve function. In some cases, poor circulation—such as in Raynaud’s phenomenon—causes numbness or cold sensations.

Less commonly, nerve compression from cysts, tumors, or certain infections like shingles or Lyme disease may be responsible.

While occasional tingling is usually harmless, persistent or recurring symptoms should be checked by a doctor.

Timely diagnosis is crucial for treating underlying conditions and preventing permanent nerve damage.
