Tingling of the fingers can be caused by completely harmless reasons, such as sleeping on your arm or temporary loss of blood supply to the limb. However in some cases tingling can be the first sign of a serious disease. Read about the 7 most common reasons why your fingers may tingle.
1. Thrombosis
Tingling of the fingers can be the result of poor blood flow, which can be caused by a blood clot. Thrombosis can lead to vessel blockage, disrupting circulation in the limbs. This condition is serious and requires immediate medical attention.
2. Damage to the nervous system
One of the other serious causes of tingling is damage to the nervous system. This can be caused by various factors, including injuries or degenerative changes in the spine that compress nerves and impair their function.
3. Multiple sclerosis
Multiple sclerosis is an autoimmune disease that destroys brain and spinal cord nerves. This process leads to loss of sensation in the limbs and gradually causes tingling of the fingers. It is a serious diagnosis that requires specialist medical monitoring.
4. Cervical osteochondrosis
This condition is related to changes in the cervical spine that cause compression of nerves and interruption of blood flow. Typical symptoms include tingling of the limbs, headaches, and problems with movement coordination.
5. Carpal tunnel syndrome
This syndrome is common in people who work with computers or perform repetitive hand movements. Swelling of the tendons in the wrist can cause compression of the nerve and lead to tingling of the fingers and their numbness.
6. Elevated blood sugar levels
Circulatory problems in the fingers and limbs are common in people with diabetes or elevated blood sugar levels. Poor blood circulation can lead to tingling of the fingers and other discomforts in the limbs.
7. Stroke or other brain damage
One of the most serious causes of tingling of the fingers can be a stroke or damage to the brain’s nerves. If, in addition to tingling, you suffer from headaches, confusion, problems with vision or speech, it is important to seek medical attention as quickly as possible, because time is crucial in such cases.
Conclusion
Tingling of the fingers can have various causes, from completely harmless to serious health conditions. If the tingling recurs without an obvious cause, do not delay seeing a doctor. Early recognition of the problem can save you many complications.
