What is numbness in hands?
Numbness in the hands is an unusual sensation that can indicate various underlying conditions. This condition, also known as paresthesia, often comes with a tingling feeling, commonly described as “pins and needles.”
Common Causes of Hand Numbness
- Nerve Issues: Compression or damage (e.g., sleeping in one position too long, carpal tunnel syndrome, herniated disc, tumors).
- Diseases: Stroke, diabetes, migraines, shingles, multiple sclerosis, Raynaud’s syndrome, thyroid disorders.
- Other Causes: Vitamin B12 deficiency, alcohol use, infections, medication side effects, electrolyte imbalances.
Diagnosis & Tests
- Medical history and physical exam.
- Blood tests, toxicology, vitamin levels, thyroid function.
- Imaging (CT, MRI, ultrasound, X-rays).
- Nerve function tests (EMG).
Treatment Options
- Home Remedies: Pain relievers, splints, heat/cold therapy, rest, hand exercises.
- Medical Treatment: Adjusting medications, treating infections, vitamin supplements, surgery (for tumors, carpal tunnel, spinal issues).
When to See a Doctor
Seek immediate medical attention if numbness is persistent or occurs with:
- Paralysis, dizziness, confusion, slurred speech.
- Numbness in other body parts, loss of bladder/bowel control.
- Rash or unexplained symptoms.
Bottom Line: Occasional numbness may not be serious, but frequent or persistent numbness requires medical evaluation.
