The feeling of numbness in your fingertips can be a symptom of many different health conditions. Some, like nerve damage or a stroke, can be serious and need immediate medical attention.
But numbness in the fingers is also often a temporary problem that usually disappears on its own. It could be the result of a sprain or strain of the wrist.
Causes
Numbness in the fingertips is caused by problems with one or more of the nerves that supply sensation to your hands. These nerves include the radial, median, and ulnar nerves. 손목통증
Damage to these nerves, or the entrapment of a nerve in a tunnel that surrounds your hand, is the most common cause of numbness in the fingertips. Other causes of numbness in the fingers include compression or irritation of a nerve in your arm or wrist.
A condition called fibromyalgia can also cause numbness in the fingers and forearms. It’s often thought to be a brain disorder that causes pain signals to be sent in an abnormal way, and may be treated with medications.
If the numbness you have is new, does not go away or becomes painful, tell your doctor. Your doctor can help diagnose the underlying problem and recommend treatment that will improve your symptoms.
Symptoms
Numbness in the fingertips is a common symptom of a number of conditions, disorders, and injuries. It can range from an occasional tingling to a severe loss of sensation that makes everyday tasks more difficult.
Most cases of finger numbness will go away on their own, but in some instances, it can indicate a serious medical issue that needs treatment right away. Depending on the underlying cause, treatment can include medication, physical therapy, and surgery. 손목결절종 수술 병원
The most common reason for numbness in the fingertips is carpal tunnel syndrome (CTS). This condition causes compression or irritation of the median nerve in the wrist, causing numbness and tingling in the thumb, index, middle, and ring fingers.
Another common condition that can cause numbness in the fingertips is ulnar nerve entrapment. This happens when the ulnar nerve that runs in the little finger’s side of the arm is trapped. This usually results in numbness in the pinky and ring fingers.
Treatment
Numbness in the fingertips is a common symptom that can be caused by many conditions. The most common cause is compression or damage to the nerves that supply sensation to the hands.
People who do a lot of work with their hands and wrists, like doctors or nurses, are at a higher risk for getting carpal tunnel syndrome (CTS). It can occur in both hands and can be very painful.
CTS causes numbness and weakness in the fingers, especially when you’re trying to type or use a computer mouse. Sometimes, it also causes numbness in the thumb and palm of the hand.
If you have numbness in your fingers and wrist, make an appointment with a healthcare provider right away. You might need to have tests for a diagnosis of the cause, such as X-rays or an MRI of your cervical spine.
Numbness in the fingers and hands that gradually gets worse is a symptom of peripheral neuropathy, which occurs when nerves are damaged from diabetes, injury, or other causes. It is usually treated by medicines to ease symptoms and reduce pain.
Prevention
Numbness in the fingertips is an uncomfortable symptom of many medical conditions. But, it can be treated, and the sooner you get help, the better your chances of recovery.
A medical doctor will start diagnosing numbness by taking your medical history and examining your arm, hand, and finger. They may also order blood tests to check your vitamin B12 levels or other underlying conditions.
If a doctor finds that the cause of your fingertip numbness is due to carpal tunnel syndrome, they may recommend surgery to reduce pressure on the median nerve. Often, this involves dividing the ligaments that support the wrist, which will give the nerve more room to move.
Carpal tunnel syndrome affects about 4-10 million Americans. This nerve disorder occurs when the bones in your wrist slip out of place, causing numbness and pain in your fingers. It can occur in any age, but it’s more common in people who use their hands a lot.
