Numbness is a reduction or loss of of normal sensation in one or both hands. Your hand may feel “asleep” or less sensitive to pain, touch, or temperature. In addition to numbness, tingling or “pins and needles” sensations are common.
Hand numbness occurs when the nerves that transmit signals from your hands to your brain are inflamed or irritated. The hand as a whole or only specific fingers may be affected, depending on the cause.
But if numbness or tingling keeps coming back, lasts longer than expected, or begins affecting your ability to use your hand, it’s your body’s way of telling you that something may not be right.
Identifying the underlying cause is the first step toward finding relief and preventing the problem from getting worse.
Common Causes of Hand Numbness and Tingling
Here are seven of the most common reasons you may be experiencing numbness and tingling in your hands.
1. Cubital Tunnel Syndrome
Not all hand numbness begins in the wrist.
Cubital Tunnel Syndrome occurs when the ulnar nerve becomes compressed as it passes along the inside of the elbow.
This nerve provides sensation to the ring finger and little finger, so symptoms are often felt in those areas.
Signs to Watch For
- Tingling in the pinky and ring fingers
- Weak grip strength
- Hand fatigue
- Pain around the inside of the elbow
- Increased symptoms when the elbow stays bent for long periods
People who frequently lean on their elbows or keep their elbows bent while sleeping may notice symptoms more often.
2. A Pinched Nerve in the Neck
Sometimes the problem isn’t actually in your hand at all.
The nerves that control your hands begin in your neck. If one of these nerves becomes compressed due to arthritis, a herniated disc, or other spinal conditions, symptoms can travel down your arm and into your hand.
This condition is often called cervical radiculopathy.
Symptoms May Include
- Neck pain
- Shoulder discomfort
- Numbness in the hand or fingers
- Tingling down the arm
- Weakness in the arm or hand
Because symptoms can resemble Carpal Tunnel Syndrome, a thorough evaluation is important to determine the true source of the problem.
3. Diabetes-Related Nerve Damage
People living with diabetes may develop peripheral neuropathy, a condition caused by damage to the nerves over time.
Although neuropathy often begins in the feet, it can also affect the hands.
Common Symptoms
- Burning sensations
- Tingling
- Numbness
- Increased sensitivity
- Muscle weakness
Managing blood sugar levels alongside rehabilitation can help reduce symptoms and improve hand function.
4. Arthritis
Arthritis doesn’t just cause joint pain—it can also contribute to numbness and tingling.
Inflammation around the joints of the hand or wrist can place pressure on nearby nerves, especially as the condition progresses.
Other Symptoms May Include
- Swollen joints
- Morning stiffness
- Pain while gripping objects
- Reduced range of motion
- Difficulty performing daily activities
Occupational therapy can help improve joint mobility, reduce discomfort, and teach strategies that protect the hands during everyday tasks.
5. Carpal Tunnel Syndrome
Carpal Tunnel Syndrome is one of the most common causes of numbness and tingling in the hands.
Inside your wrist is a narrow passageway called the carpal tunnel, which protects the median nerve. When this tunnel becomes crowded due to swelling or inflammation, the nerve is compressed, leading to uncomfortable symptoms.
Common Symptoms
- Numbness in the thumb, index, middle, and part of the ring finger
- Tingling that is often worse at night
- Hand weakness
- Difficulty gripping objects
- Frequently dropping items
People who spend long hours typing, using tools, or performing repetitive hand movements are at a higher risk of developing Carpal Tunnel Syndrome.
Fortunately, many cases respond well to early treatment with occupational and hand therapy.
6. Repetitive Strain Injuries
Many people use their hands for thousands of repetitive movements every day without realizing how much stress they’re placing on their muscles and tendons.
Common repetitive activities include:
- Typing
- Using a computer mouse
- Texting
- Sewing
- Gardening
- Assembly work
- Using hand tools
Over time, repeated movements can irritate tendons and surrounding tissues, increasing pressure on nearby nerves and causing numbness, tingling, or weakness.
Making ergonomic adjustments and taking regular movement breaks can go a long way toward preventing these injuries.
7. Previous Injuries to the Hand or Wrist
If you’ve had a fracture, sprain, tendon injury, or surgery involving your hand or wrist, lingering numbness may be part of the healing process.
Scar tissue, swelling, or changes in joint mechanics can sometimes place pressure on nearby nerves long after the initial injury has healed.
Without proper rehabilitation, stiffness and weakness may also contribute to ongoing symptoms.
Occupational and hand therapy can help restore mobility, improve strength, and reduce nerve irritation following an injury.
When Should You Seek Immediate Help?
Occasional numbness that resolves quickly is usually not a cause for concern.
However, you should consider scheduling an evaluation if:
- Numbness occurs frequently.
- Tingling wakes you up at night.
- Symptoms continue for several days or weeks.
- You notice weakness in your hand.
- You’re dropping objects more often.
- Pain interferes with work or daily activities.
- Symptoms continue to worsen over time.
- Occurs with weakness on one side of the body.
- Is accompanied by facial drooping or difficulty speaking.
- Follows a serious injury to the head, neck, or spine.
- Is associated with severe neck pain and loss of bladder or bowel control.
Early treatment often prevents symptoms from becoming more severe and may reduce the need for more invasive treatments later.
Other suspected causes may include;
Hand numbness can result from a wide range of conditions affecting the nerves, blood vessels, muscles, joints, or even the brain and spinal cord. While common causes like Carpal Tunnel Syndrome, Cubital Tunnel Syndrome, arthritis, and repetitive strain injuries account for many cases, there are several other possible causes.
Other Suspected Causes of Hand Numbness
- Thoracic Outlet Syndrome which is the compression of nerves or blood vessels between the collarbone and first rib can cause numbness, tingling, shoulder pain, and weakness in the arm and hand.
- Peripheral Neuropathy
- Vitamin B & E Deficiencies
- Diabetes.
- Multiple Sclerosis (MS)
- Stroke or Transient Ischemic Attack (TIA)
- Ganglion Cysts
- Wrist or Hand Fractures
- Tendon Inflammation (Tendonitis)
- Rheumatoid arthritis
- Lupus
- Sjögren’s syndrome
- Vasculitis
- Shingles (Herpes zoster)
- HIV
- Hepatitis C
- Lyme disease
- Chemotherapy drugs
- Certain antibiotics
- Some anticonvulsants
- Alcohol-Related Nerve Damage
