Hand pain at night: Why does it happen and how to improve it?

Possible causes of hand pain at night

Nighttime hand pain can have very different origins, ranging from nervous or inflammatory issues to postural or circulatory factors. Identifying the cause is important because the treatment may vary depending on the origin of the symptom. Below are the most common causes.

Carpal Tunnel Syndrome

Carpal Tunnel Syndrome occurs when the median nerve is compressed as it passes through the wrist. It typically causes tingling, numbness, and nighttime pain, especially in the thumb, index, and middle fingers. In many cases, there is also a noticeable loss of strength or clumsiness when handling objects, to the point where "things fall from the hands."

Arthritis

Arthritis causes inflammation in the joints of the hand and wrist, which can lead to pain, stiffness, and limited movement. At night, discomfort usually increases because the joint remains at rest for a longer period, which promotes morning stiffness and the feeling of "locked" hands upon waking.

Tendinitis

Tendinitis is related to the overuse of the flexor or extensor tendons of the hand and wrist, something common in repetitive tasks or sustained effort. Pain is often accompanied by a feeling of stiffness, especially when moving the hand after a period of rest. In some cases, inflammation or discomfort may also appear when performing everyday gestures.

Fluid Retention

Fluid retention can cause swelling in the hands and wrists, increasing pressure on nerves and tendons. It is a common symptom during pregnancy, but it can also occur in people with conditions affecting the kidneys or other conditions that disrupt the fluid balance. This extra pressure can make the pain more intense at night or upon waking.

Improper Sleeping Postures

When sleeping, it is common to adopt positions that keep the wrist flexed or bent for hours, or even rest the body weight on the hands. These positions can compress nerves, irritate tendon structures, and promote tingling or nighttime pain. In many people, simply correcting the posture can lead to improvement.

Circulatory Problems

During sleep, the heart rate decreases and blood flow can become somewhat slower, especially in the extremities. In some people, this leads to feelings of coldness, tingling, or pain in the hands, especially if there are additional factors like poor posture or sustained compression. In these cases, the symptom usually improves when moving the hands or changing position.

Tips to improve hand pain at night

In many cases, nighttime hand pain can be relieved with small changes in routine and sleeping posture, as well as simple measures to reduce inflammation or accumulated tension. These recommendations help to decrease pressure on nerves and tendons and are often a good first step before considering a more specific treatment.

• Maintain a neutral posture: avoid bending the wrists while sleeping.
• Use night splints to keep the wrist straight.
• Perform gentle stretches before going to bed.
• Apply cold or hot compresses depending on the cause of the pain.
• Avoid sleeping on your hands or with clenched fists.
• Consult a doctor if the pain persists for more than two weeks or is accompanied by a loss of strength.

When to see a specialist for hand pain at night

In some cases, nighttime hand pain may be the manifestation of a problem that requires a specific medical evaluation. Recognizing when discomfort stops being a one-off issue and needs professional attention is key to making an accurate diagnosis and applying the most appropriate treatment.

• Severe pain that doesn't improve with basic measures.
• Constant tingling sensation or loss of sensitivity.
• Weakness in the hand that makes everyday tasks difficult.
