Most often, tingling and numbness in the hands occur due to poor posture, typically prolonged pressure on the arm which compresses the peripheral nerves. The symptom, in this case, is not severe, but other disorders can be the cause of this sensation.

Definition And Symptoms

Tingling is the expression of paresthesia:  a touch disorder that includes tingling, numbness, and tingling in a limb, usually in the extremities. This tingling can affect the hands, some fingers, but also the face and legs. Most often, tingling in the hands occurs due to compression of a nerve in the arm.

Causes

Paresthesia is usually caused by dysfunction of the peripheral nerves or the central nervous system.

Carpal Tunnel Syndrome

Apart from the minor tingling due to improper support or positioning, the most common cause is carpal tunnel syndrome: compression of the median nerve at the wrist causes these numbness and tingling sensations, especially during the night or in the morning when you wake up.

These disorders can be accompanied by weakness in the wrist or hand. This syndrome most often appears following repetitive actions performed in a professional environment. The carpal tunnel is not the only one to cause these symptoms: compression of the ulnar canal at the elbow level can also generate tingling in the hands.

Diabetes

Namely, people with diabetes, at a relatively advanced stage of the disease, are also concerned by the appearance of tingling: we speak of “diabetic neuropathy” due to high levels of sugar and fat in the blood, which alter nerve endings. However, in this case, tingling appears most often in the legs and feet, more rarely in the hands.

Spasmophilia

An attack of spasmophilia can also cause tingling in the hands. Other characteristic symptoms then appear as anxious state, muscle spasms, accelerated breathing, etc.

An Early Sign Of A Stroke

Suppose this tingling is more like a form of hand numbness (มือ ชา which is the term in Thai), a weakness in the hands. In that case, it can suggest a warning sign of a cerebrovascular accident (stroke), especially if the person concerned is one of the people said at risk (known vascular problems, hypertension, cholesterol, etc.).

Raynaud’s Syndrome Or Disease

Raynaud’s disease is a chronic blood circulation condition that affects the extremities (fingers, toes, nose, and ears). It manifests itself in fits, in which the fingers turn white and cold, then blue, and finally red and swollen. These attacks also cause numbness in hand and tingling sensations.
