A tingling sensation in the thumb is often ignored, but it can be a sign of a serious medical condition.
The most common cause is carpal tunnel syndrome. This is when the median nerve in your wrist becomes compressed.
This causes numbness and tingling in the thumb, index finger, middle finger, and sometimes the ring finger.
However, it is important to consult a doctor to determine the exact cause and appropriate treatment, especially if other symptoms such as weakness in the hand are also occurring.
If this condition, carpal tunnel syndrome, is left untreated, this nerve damage can lead to possible weakness in the hand, making it difficult to grip objects.
Similarly, thumb tingling can sometimes be caused by other underlying medical conditions, such as diabetes, vitamin deficiencies, or cervical radiculopathy (a compression of a nerve in the neck).
