Hand Weakness: Why Do My Hands Feel Weak?

Noticing weakness in your hands, whether it comes on slowly or feels sudden, can be frustrating. It can also be alarming.

You might struggle to hold small objects. Everyday tasks like typing, opening a jar, or buttoning a shirt may become unexpectedly difficult.

Persistent or worsening hand weakness requires a medical evaluation.

Why Do My Hands Feel Weak?

Hand weakness can stem from a variety of possible causes. Some are temporary and harmless, while others may need medical treatment.

Weakness can come from problems with the nerves, muscles, or joints in the hand. It can result from issues in your neck or spine. It may also be due to age-related muscle loss.

Some of the most common causes are:

1. Carpal tunnel syndrome

This happens when a major nerve, the median nerve, gets squeezed at the wrist. It often leads to weakness, numbness, or tingling in the thumb, index, and middle fingers. You may drop objects or find it harder to pinch or grip things.

2. Cubital tunnel syndrome

This condition affects the ulnar nerve, which runs along the inside of your elbow. If it’s compressed, you may feel weakness or tingling in your ring and pinky fingers. It can be caused by leaning on your elbows or keeping them bent for long periods.

3. Pinched nerve in the neck

The nerves that control your hands begin in your spinal cord and travel down your arms. If one of these nerves gets compressed or irritated near your neck, a condition known as cervical radiculopathy, it can cause weakness in your arms and hands. You might also notice pain or numbness radiating from the neck to your fingers.

4. Herniated Disc

Similar to a pinched nerve in the neck, a herniated disc in the cervical spine can put pressure on nerves. It can cause radiating pain down to your hands and can lead to hand weakness.

5. Arthritis

Osteoarthritis, caused by wear and tear, and rheumatoid arthritis, an autoimmune condition, can both impact the small joints in your hands. Over time, joint damage can lead to:

Muscle weakness
Stiffness
Reduced grip strength

6. Peripheral neuropathy (PN)

This is a condition where the nerves in your arms and hands are damaged. The damage can result from other health issues like diabetes or even vitamin deficiencies. PN can cause weakness, numbness, or burning sensations in the hands.

7. Overuse or repetitive strain injuries

Using your hands for the same motion over and over, as in typing or playing an instrument, can lead to muscle fatigue and inflammation of the tendons or nerves. Strain may cause temporary weakness or pain with certain movements.

8. Ganglion cysts

Small, fluid-filled lumps can form near joints or tendons in the wrist or hand. If they press on a nerve, they can cause discomfort or weakness.

9. Stroke or neurological conditions

A sudden loss of strength in one hand, especially if paired with facial drooping, slurred speech, or arm numbness, could be a sign of a stroke.

Strokes occur when blood flow to the brain is interrupted and require immediate emergency care. Quick treatment can prevent long-term brain injury, and every minute counts.

See A Doctor for Hand Weakness

It’s a good idea to talk to your doctor if:

Your hand weakness is getting worse
You have trouble holding objects or doing daily activities
Weakness is accompanied by numbness, tingling, or pain
You notice sudden weakness in one hand or arm

Getting the correct diagnosis is the first step in restoring function and preventing further problems.
