Tingling in hands and feet can result from poor blood circulation, nerve damage, nutritional deficiencies, medical conditions, and injuries. Treatment requires identifying the underlying cause, and seeing a doctor if accompanied by other symptoms.
Tingling in the hands and feet can result from poor blood circulation, nerve damage, nutritional deficiencies, or the presence of a wide range of medical conditions. Sitting in one position for too long can reduce blood circulation and is a common cause of tingling in the hands and feet. Injuries and medical conditions that cause nerve damage or put pressure on nerves can lead to pins and needles. Medications and radiation therapy can, in some cases, lead to a tingling sensation.
Poor blood circulation can sometimes cause tingling in the hands and feet. Standing or sitting in one particular position for too long can inhibit proper blood circulation. Atherosclerosis is a medical condition in which the buildup of cholesterol can lead to blockage of arteries and blood circulation. Dealing with extremely cold weather can inhibit proper blood circulation, leading to tingling in your hands and feet.
Nerve damage is another cause of tingling sensations. A man who has injured his neck in a car accident may experience tingling in his arm or hand. Lower back injuries from lifting heavy objects, for example, can cause nerve damage and pinched nerves, resulting in a tingling sensation. A typist might experience carpal tunnel syndrome, which affects the nerves in the wrists and can cause pins and needles.
Toxic elements in the body can also cause nerve damage. An individual who drinks alcohol or smokes excessively is more prone to toxic nerve damage and may experience tingling sensations. Lead is another toxic substance that can damage nerves. Some medications can also cause toxicity, leading to pins and needles. Radiation therapy is another possible cause of pins and needles caused by nerve damage.
Some medical conditions put pressure on the nerves, causing tingling sensations. An infection can cause swelling and pressure on the nerves. The presence of large tumors affecting the nerves is another possible reason behind the pins and needles sensations. Health conditions that cause blood vessels to widen can also put pressure on the nerves, leading to pins and needles.
In some cases, tingling in the hands and feet is the result of nutritional deficiencies. A vitamin B12 deficiency can cause tingling sensations. Potassium, sodium and calcium deficiencies can also cause this problem. In these cases, making sure nutritional needs are met usually reduces or eliminates the tingling sensations.
Treatment for tingling hands and feet requires uncovering the underlying cause of the problem. If the sensation is caused by sitting or standing in one position for too long, the cause is clear as the tingling goes away within minutes. When the cause isn’t clear, however, a doctor will usually ask about the location of the tingling, how long it’s been a problem, and whether it’s accompanied by other symptoms. You should see a doctor right away if paralysis, blurred vision, confusion, or muscle weakness accompany the tingling.
