Tingling fingers and numb feet are potential signs of diabetic neuropathy. Diabetic neuropathy is a condition that results from nerve damage. Diabetic neuropathy is a common condition among diabetics.

There are four main types of diabetic neuropathy, with the symptoms depending upon the type of neuropathy present in the person with diabetes. Your doctor will determine if you have peripheral neuropathy, focal neuropathy, autonomic neuropathy, or proximal neuropathy.

Peripheral neuropathy affects the nerves of the feet and legs first and then goes to the hands and arms. It is the most common type of neuropathy.

Symptoms include numbness or tingling in the extremities, burning or a sensation similar to an electrical shock, muscle cramping, twitching or weakness, sensitivity to touch, or poor coordination.

Focal neuropathy, or mononeuropathy, is damage to a specific nerve. Entrapment syndromes, such as carpal tunnel, are examples of focal neuropathies. It may lead to numbness or tingling of the fingers, hand weakness, stomach pain, shin, or foot pain. It usually does not cause long-term issues.

Autonomic neuropathy can cause issues anywhere in the autonomic system. The autonomic system controls the eyes, lungs, bladder, sex organs, stomach, and intestines. Some symptoms include changes in heart rate, sudden drop in blood pressure, issues with regulating body temperature, and gastrointestinal issues.

Proximal neuropathy, or diabetic polyradiculopathy, affects nerve endings of the legs, thighs, buttocks, or hips. It is a rare neuropathy that can cause symptoms on one side, along with difficulty getting up when seated, severe or sudden pain in the stomach, buttocks, hips, or thighs.

Report all symptoms of finger tingling, foot numbness, or other signs of neuropathy to your doctor without delay.
