Hand numbness can be uncomfortable, distracting, and sometimes difficult to explain. Occasional numbness and tingling may develop after sleeping in an awkward position or using your hands repeatedly, but persistent numbness may point to an underlying cause that needs attention, such as carpal tunnel syndrome.
This article explains common causes of numbness, the early signs of carpal tunnel syndrome, everyday activities that can trigger symptoms, at-home treatments, and when to seek medical attention.
If you are experiencing persistent numbness or other symptoms, Precision Orthopaedic Specialties can help determine the right diagnosis and develop a personalized treatment plan. Schedule an appointment at one of our Ohio locations in Chardon, Chagrin Falls, and Middlefield.
Numbness occurs when nerves cannot properly send signals between the hand and brain. The underlying cause may involve pressure on a nerve, nerve damage, blood vessels, or another underlying condition.
A pinched nerve in the neck, known as cervical radiculopathy, can cause symptoms that travel from the neck into the shoulder, arm, and hand. Ulnar nerve compression may cause numbness or tingling primarily in the ring and pinky fingers. Peripheral neuropathy can also cause numbness and may be associated with certain medical conditions or medications.
Sometimes, a temporary sleeping position or pressure on the arm can cause a brief “needles feeling.” However, persistent numbness should not be ignored.
Carpal tunnel syndrome develops when the median nerve becomes compressed as it travels through a narrow passageway called the carpal tunnel in the wrist. The median nerve provides sensation to the thumb, index, middle, and part of the ring finger.
When the condition occurs, pressure on the median nerve can cause numbness and tingling. Symptoms may have a gradual onset and initially come and go. Repetitive hand use can make them more noticeable.
One of the earliest signs is numbness or tingling in the thumb, index, and middle fingers. Many people notice symptoms at night and may wake up with numb hands, then shake or move the hand to relieve the sensation.
Other symptoms may include aching, burning, weakness, or difficulty with fine motor tasks. As carpal tunnel progresses, some people may have trouble gripping objects or notice that they are dropping things.
Repetitive activities that require frequent wrist or hand movements can aggravate carpal tunnel symptoms. These may include typing, using a mouse, gripping tools, driving, playing certain sports, or working with handheld equipment.
Activities such as yard work with leaf blowers, chain saws, or snow blowers may also increase hand symptoms because of repetitive gripping and vibration. Taking regular breaks and changing hand positions can help reduce pressure on the median nerve.
Mild symptoms may improve with conservative treatment. A wrist splint can help keep the wrist in a neutral position, particularly while sleeping. Avoiding activities that worsen symptoms and taking regular breaks may also help.
Gentle stretching and physical therapy exercises may improve flexibility and reduce irritation. Over-the-counter anti-inflammatory medications may help some people, although they are not appropriate for everyone. Talk with a healthcare professional before using medications or supplements to treat nerve symptoms.
If numbness becomes frequent, lasts longer, or interferes with work, sports, sleep, or everyday activities, it is time to seek medical attention. Weakness, difficulty gripping objects, or persistent numbness can indicate more significant nerve compression or nerve damage.
Some symptoms require immediate medical attention. Sudden numbness accompanied by slurred speech, facial weakness, severe dizziness, or other sudden neurological symptoms may indicate a medical emergency.
A healthcare professional will review your symptoms, medical history, activities, and physical examination findings. They may check sensation, strength, and how the nerves function in the hand and arm.
Nerve conduction studies and other tests may be used to determine whether the median nerve is compressed and how severe the problem may be. These tests can also help distinguish carpal tunnel from other causes of numbness, including ulnar nerve compression and cervical radiculopathy.
When conservative treatment does not provide enough relief or nerve compression is severe, surgical procedures may be considered. Carpal tunnel release surgery creates more space for the median nerve by releasing the tissue forming the roof of the carpal tunnel.
Carpal tunnel release is commonly performed as an outpatient procedure. Recovery varies depending on the individual, the severity of the condition, and the procedure performed. Your orthopaedic specialist can explain expected recovery and when you can safely return to work, sports, and other activities.
You may be able to reduce symptoms by keeping your wrists in a neutral position, taking breaks during repetitive activities, and avoiding prolonged pressure on the wrists. Adjusting your workstation and changing how you grip tools can also help.
Pay attention to early symptoms rather than waiting for them to become severe. Addressing the underlying cause early may help prevent symptoms from worsening or spreading upward into the arm.
If you have persistent numbness, weakness, or a tingling sensation that is affecting your daily activities, Precision Orthopaedic Specialties can evaluate your symptoms and discuss appropriate treatment options. Schedule an appointment at our Chardon, Chagrin Falls, or Middlefield, Ohio locations to get started with a personalized treatment plan.
Numbness at night may occur when your sleeping position keeps the wrist bent or places pressure on a nerve. Repeated nighttime symptoms are also a common early sign of carpal tunnel syndrome.
Carpal tunnel typically affects the thumb, index, middle, and part of the ring finger because these areas receive sensation from the median nerve.
Yes. A pinched nerve in the neck, known as cervical radiculopathy, or compression of the ulnar nerve can cause numbness and other symptoms in the hand and arm.
Physical therapy may be included in a conservative treatment plan for some patients. Exercises, activity modifications, and other techniques may help improve movement and reduce pressure on irritated nerves.
