7 Possible Weakness In One Hand Causes

The list below shows results from the use of our quiz by Buoy users who experienced weakness in one hand. This list does not constitute medical advice and may not accurately represent what you have.

Carpal tunnel syndrome

Carpal tunnel syndrome is a condition of numbness and tingling in the hand and arm caused by compression of the mediannerve as it travels through the carpal tunnel. Causes include overuse of the wrist and hand, especially highly repetitive activities such as typing or working on an assembly line. Injuries can damage the carpal tunnel, as can arthritis, diabetes, and obesity.

Symptoms include(https://www.buoyhealth.com/symptoms-a-z/weakness-in-both-hands/) when trying to hold an object. Carpal tunnel syndrome gets worse over time and may lead to permanent damage if not addressed.

Treatment options include supportive devices, stretching exercises, medications, and surgery.

Rarity: Common

Top Symptoms: spontaneous shoulder pain, hand weakness, wrist pain, weakness in one hand, pain in both hands

Urgency: Primary care doctor

Ulnar nerve entrapment of elbow

Ulnar nerve entrapment of elbow is also called cubital tunnel syndrome. The ulnar nerve begins at the spinal cord in the neck and runs down the arm into the hand. This very long nerve can become compressed, or entrapped, by other structures at certain points along the way. Entrapment often happens in the cubital tunnel, which is the narrow passage at the inside of the elbow.

The exact cause for entrapment may not be known. Fluid buildup and swelling inside the elbow; previous elbow fracture or dislocation; or leaning on the elbow for long periods of time can put pressure on the ulnar nerve inside the cubital tunnel.

Symptoms include numbness and tingling of the hand and fingers, sometimes leading to weakness and even muscle wasting in the hand.

Diagnosis is made through physical examination, x-ray, and nerve conduction studies.

Treatment begins with wearing a supportive brace and adjusting activities to avoid further irritating the nerve. Surgery is usually not needed unless the nerve compression is causing weakness and loss of use in the hand.

Rarity: Common

Top Symptoms: hand weakness, weakness in one hand, numbness in one hand, pain in one elbow, pain in one forearm

Urgency: Primary care doctor

Tennis elbow (lateral epicondylitis)

Tennis elbow, or lateral epicondylitis, is an inflammation of the tendons that connect the muscles of the forearm to the side of the elbow.

It is caused by using the arm in repetitive motion, such as swinging a tennis racquet. The forearm muscles become weakened and damaged from overuse, putting strain on the tendons.

Most susceptible are people over 30 who work using overhead motion of the arm. Auto mechanics, painters, carpenters, and butchers are often affected, as well as anyone playing racquet sports,.

Symptoms begin gradually and consist of burning pain on the outside of the elbow, with loss of grip strength.

Diagnosis is made through physical examination with simple neurological tests that use the forearm muscles, such as shaking hands. X-rays or MRI may also be ordered.

Treatment involves rest; nonsteroidal anti-inflammatory pain relievers; physical therapy; an arm brace just below the elbow; and sometimes steroid injections. Surgery is rarely needed.

Using the right equipment, as well as proper technique for overhead motions of the arm, can help prevent the condition.

Rarity: Common

Top Symptoms: elbow pain, pain in one elbow, hand weakness, pain in the thumb side of the elbow, elbow pain from overuse

Symptoms that always occur with tennis elbow (lateral epicondylitis): elbow pain

De quervain's tenosynovitis

De Quervain's tenosynovitis is a painful condition affecting the tendons on the thumb side of the wrist. If you have de Quervain's tenosynovitis, you will feel pain upon turning your wrist, grasping anything, or making a fist.

Rarity: Uncommon

Top Symptoms: hand numbness, thumb pain, hand weakness, weakness in one hand, numbness in one hand

Symptoms that always occur with de quervain's tenosynovitis: thumb pain

Urgency: Primary care doctor

Stroke or tia (transient ischemic attack)

Transient ischemic attack, or TIA, is sometimes called a "mini stroke" or a "warning stroke." Any stroke means that blood flow somewhere in the brain has been blocked by a clot.

Risk factors include smoking, obesity, and cardiovascular disease, though anyone can experience a TIA.

Symptoms are "transient," meaning they come and go within minutes because the clot dissolves or moves on its own. Stroke symptoms include weakness, numbness, and paralysis on one side of the face and/or body; slurred speech; abnormal vision; and sudden, severe headache.

A TIA does not cause permanent damage because it is over quickly. However, the patient must get treatment because a TIA is a warning that a more damaging stroke is likely to occur. Take the patient to the emergency room or call 9-1-1.

Diagnosis is made through patient history; physical examination; CT scan or MRI; and electrocardiogram.

Treatment includes anticoagulant medication to prevent further clots. Surgery to clear some of the arteries may also be recommended.

Rarity: Common

Top Symptoms: dizziness, leg numbness, arm numbness, new headache, stiff neck

Symptoms that never occur with stroke or tia (transient ischemic attack): bilateral weakness

Urgency: Emergency medical service

Amyotrophic lateral sclerosis (als)

Amyotrophic lateral sclerosis is also called ALS or Lou Gehrig's Disease named after the Hall of Fame baseball player whose career ended when he developed ALS. It is a degenerative disease that destroys nerve cells, which eventually leads to loss of control over muscle function. The cause of ALS is not known.

Symptoms include weakness; difficulty with speaking, swallowing, walking, or using the hands; and muscle cramps. It does not affect the senses or a person's mental ability.

ALS is progressive, meaning it worsens over time. There is no cure, but supportive care can keep the patient more comfortable and improve quality of life. Treatment involves medications to both slow the progression of the disease and ease the symptoms; respiratory therapy; physical therapy; occupational therapy; and psychological support.

Rarity: Ultra rare

Top Symptoms: shortness of breath, decreased exercise tolerance, difficulty concentrating, difficulty walking, hoarse voice

Urgency: Primary care doctor

Pinched nerve in the neck

A pinched nerve in the neck is also called cervical radiculopathy. It means that a nerve in the neck, at a point where it branches off from the spinal cord, is being compressed by the surrounding bones, muscles, or other tissues.

It can be caused by a traumatic injury, such as from sports or an automobile accident, especially if the injury results in a herniated disk. It may also arise from the normal wear and tear of aging.

Symptoms include sharp, burning pain with numbness and tingling from the neck to the shoulder, as well as weakness and numbness into the arm and hand.

Diagnosis is made through patient history, physical examination, and simple neurological tests to check the reflexes. Imaging such as x-ray, CT scan, or MRI may be done, as well as electromyography to measure nerve impulses in the muscles.

A pinched nerve in the neck often improves with simply a few days or weeks of rest. Physical therapy, nonsteroidal anti-inflammatory drugs, and steroid injections into the spine can all be very helpful.

Rarity: Common

Top Symptoms: pain in one shoulder, spontaneous shoulder pain, pain that radiates down arm, pain in the back of the neck, severe shoulder pain

Urgency: Primary care doctor

Questions Your Doctor May Ask About Weakness In One Hand

To diagnose this condition, your doctor would likely ask the following questions:

  • What is your body mass?
  • Have someone feel for your pulse (at the wrist) on the side of your body that hurts. Now, turn your head to that side. Does the pulse go away? (This is known as the Adson's test.)
  • Turn your head toward the side of your body that is hurting. Lift your head up as someone else pushes down on your head. Does this cause greater pain in your upper body? (This is known as Spurling's test.)
  • Lightly tap on your inner wrist. Does this cause your symptoms to reappear?

The above questions are also covered by our A.I. Health Assistant.
