5 reasons why your hands might be tingling

1  Your limb fell asleep

Almost everyone has experienced having an arm or leg “fall asleep,” when the limb feels heavy and tingly, like pins and needles are pricking it, when you go to move. Luckily, once you get moving, it relieves pressure on the nerve and the uncomfortable tingly sensation will resolve in a few seconds in most healthy individuals.

2  Radiculopathy

Radiculopathy occurs when there’s a pinched nerve, usually in the spinal cord, which can cause a range of symptoms, including tingling. A pinched nerve is diagnosed using imaging machines like an x-ray or MRI.

3  Carpal tunnel syndrome

Carpal tunnel syndrome is a very common cause of tingling in the hands. Usually, the tingling is accompanied by pain, numbness, and weakness, but typically only in one hand. It affects all the fingers except the pinky. Carpal tunnel is typically diagnosed by an initial physical exam followed by electrodiagnostic testing, which measures the strength and speed of the electrical signal from the median nerves into the surrounding muscles in your wrist and fingers.

4  Fibromyalgia

Fibromyalgia is a condition that causes pain throughout the body, and can also trigger tingling in the hands. Fibromyalgia is a difficult diagnosis to make and typically made after excluding other overlapping disorders.

5  Diabetic neuropathy

Diabetic neuropathy can cause tingling in the fingers, often accompanied by numbness that doesn’t go away. There’s no treatment for peripheral neuropathy, but controlling your blood sugar levels can keep it from getting worse.
