Tingling in the hands is a common symptom of carpal tunnel syndrome, a very common disorder that affects the mobility and sensitivity of the hands.
What is known as carpal tunnel syndrome is a frequent disease that, according to the latest statistics, affects about 3% of the general population, with a higher incidence in the population of workers with significant physical activity in the hands.
It consists of a peripheral neuropathy that arises when the median nerve (which runs from the forearm to the hand), is trapped or pressed within the carpal tunnel, specifically at the level of the wrist.
This nerve controls the impulses of some small muscles in the hand that, among other aspects, allow the mobility of the fingers and thumb, and also controls the sensations of the front part of the fingers of the hand (except the little finger).
Among its most common symptoms, you usually feel heat, cramp or numbness in the fingers and in the palm of the hand, especially in the thumb and in the index and middle fingers. Also, even if there is no apparent swelling, it is common for the fingers to feel swollen and useless.
In this sense, feeling tingling in the hands is usually one of the symptoms also related to this syndrome, which is felt specifically in the thumb, as well as in the second and third toes.
This tingling tends to increase gradually (like the rest of the symptoms), which can cause pain, changes in sensitivity to touch and loss of strength.
For this reason, before the first related symptom that appears, it is advisable to consult a doctor, who will diagnose the possible existence of carpal tunnel syndrome and identify its cause (for example, in the case of secondary carpal tunnel, its cause may be obesity, diabetes, rheumatoid arthritis, infections…) for which the primary cause must first be treated.
In those cases in which there is no apparent cause, prevention is recommended, adopting less traumatic wrist movement habits, resting from time to time.
Since one of the causes is the continued use of the computer (especially both the keyboard and the mouse), it is advisable to change the keyboard to a more suitable one and use a suitable mouse pad to rest the wrist.
