Tingling is a tingling sensation and numbness in the limbs, often felt in the hands, fingers, legs, or face. These symptoms can be caused by a variety of factors, including poor blood circulation, nerve pressure, vitamin or mineral deficiency, prolonged poor posture, exposure to extreme temperatures, or even underlying neurological disorders. Therefore, it is important to see a doctor if you experience frequent or persistent tingling, to determine the underlying cause and receive the appropriate treatment.
Bad posture at work
A chronically numb hand can be caused by repetitive tasks or an awkward posture at work. Possible causes include using a computer, holding a mouse improperly, tension in the head or spine, or using vibrating tools.
Spasmophilia
An attack of spasmophilia can cause tingling in the hands, as well as anxiety, muscle spasms and rapid breathing.
An early sign of a stroke
Tingling, weakness or numbness in the hands can be a warning sign of a stroke, especially if you are at risk due to known vascular problems, high blood pressure, cholesterol or other factors of risk, as Dr. Handschuh explains.
Diabetes
People with advanced diabetes may suffer from tingling, called “diabetic neuropathy”. This condition is caused by high levels of sugar and fat in the blood, which damage nerve endings. Tingling is mainly felt in the legs and feet, and rarely in the hands, according to doctors.
Raynaud’s disease
Raynaud’s disease is a chronic blood circulation disease that affects the extremities such as the fingers, toes, nose and ears. It causes attacks with whitening and cooling of the fingers, followed by blueness, reddening and swelling. They also cause loss of sensation and tingling in the hand.
Multiple sclerosis
Multiple sclerosis can cause numbness in the hands and legs, as well as problems with vision, incontinence, fatigue and balance due to inflammation of the spinal cord.
Vitamin B12 deficiency
Vitamin B12 deficiency in alcoholics and the elderly can cause pain and tingling in the hands, which may indicate an underlying disease such as multiple sclerosis affecting the central nervous system.
carpal tunnel syndrome
Tingling and numbness can be caused by poor posture, but more often carpal tunnel syndrome is to blame. This syndrome occurs when the median nerve is compressed at the wrist, causing numbness and tingling sensations, particularly at night or upon waking in the morning. Symptoms may be accompanied by hand or wrist weakness. Carpal tunnel syndrome is often linked to repetitive movements at work. Dr. Handschuh, a general practitioner, indicates that these symptoms can also be caused by compression of the ulnar canal at the elbow.
A bad position while sleeping
If you feel numbness in your hand as soon as you wake up, it may be due to your sleeping position. These tingling sensations in the limbs are not serious and go away on their own.
When to consult and what treatment?
If you experience frequent, intense, or spreading tingling, see a doctor. The latter can refer you to a neurologist for more in-depth examinations if necessary. If the tingling appears suddenly together with other symptoms such as speech impairment, weakness on one side of the body, loss of balance and/or visual disturbance, contact the emergency services immediately: this may indicate a transient ischemic attack (TIA) or stroke. If your limb is just numb, movement is often enough to make the tingling go away. In case of confirmed carpal tunnel syndrome, correct your risky postures to observe spontaneous healing. Otherwise, consider surgery.
