Getting numb fingertips is a common condition for many people. The numbness can be mild or severe. This condition can interfere with everyday activities. Numbness can be due to infections, pressure on nerves, or other problems. Depending on the cause of the numbness, treatment may include pain relief medication, splints, and physical therapy. Other causes can include problems with the brain or spinal cord. A doctor will evaluate your symptoms and may perform a variety of tests to determine the cause of your condition.
The most common cause of numb fingertips is carpal tunnel syndrome, a condition that causes pain in the wrist. This condition is caused by compression of the median nerve, which is located in the wrist. Repetitive motions that cause the wrist to become inflamed may also contribute to carpal tunnel syndrome. There are several symptoms of carpal tunnel syndrome, including pain, stiffness, and numbness in the wrist. The symptoms may be controlled with medication or lifestyle changes.
Another common cause of numb fingertips is ganglion cysts. These cysts are often harmless but may press on the nerve. If a cyst does not shrink, it may need to be removed by a doctor. Symptoms of ganglion cysts include numbness and tingling in the hand or fingers. They usually disappear with rest.
Other conditions that may cause numb fingertips include diabetes, hypocalcemia, hypomagnesemia, and hyperventilation. These conditions can also cause transient symptoms, such as pain or tingling in the fingertips. The numbness can last for hours or days. In some cases, a doctor will perform a nerve conduction test to see if carpal tunnel syndrome is the cause of the numbness.
Numb fingertips can also occur after an injury. If you have a cut on your fingertips, it may take a few days for the swelling to go away. You may also have a rash. A rash can appear anywhere on the body, including the fingertips. It is common for a rash to appear if you have food allergies.
Repetitive motions that involve the wrist can also cause numb fingertips. For example, people who work on a computer or do other similar activities that require long hours of flexion of the wrist may experience numbness in the hands. If you have these conditions, it is recommended that you take breaks every 45-60 minutes. You should also practice good posture. Using a mouse mat can help support your wrist and keep it from spraining.
Numbness may also be caused by problems with blood circulation. Blood flow in the hands can be cut off when the arm is bent for a long time. When the arteries that supply blood to the hands are blocked, they become inflamed and may cause thrombosis. If this is the cause of the numbness, surgical removal of the embolus can help. 손끝저림
