On the other hand, too much vitamin B6 can cause pins and needles in the hands and feet.Īlcoholism and toxins are troublemakers once again. For example, a B12 deficiency can cause pernicious anemia, a substantial cause of peripheral neuropathy. Vitamins B1, B6, B12, E, and niacin are crucial to a well-functioning nervous system. Vitamin deficiencies can also cause the tickly feeling. Diabetes - About two-thirds of people with diabetes have some form of nerve damage.Toxic substance effect on nerves (drugs, alcohol, lead).Pinched nerve from carpal tunnel syndrome, vertebral subluxations, or misaligned joints.Hyperventilation or excessive breathing.Like any other medical condition, the sooner your underlying cause is pinpointed, the more likely it can be brought under control, and long-term consequences can be prevented. Smoking also restricts blood flow and can contribute to the sensation, which could be a sign of a greater problem. It is not only wise but important to seek timely medical assessment for any persistent tickling or tingling in your hands, feet, or both. Tingling is not cause for concern unless it is frequently happening and for more than about 90 seconds at a time. The tingling comes when nerves resume functioning and communicate with the brain and spinal cord again, sending initially spotty signals to feel pain. Our innate reaction is to shake the limb, which speeds and encourages blood flow again. It starts out as a numb, heavy feeling, and turns into a lightweight, tingly response for 30 to 90 seconds in total. We tend to create this ourselves by sitting, lying, or leaning for a prolonged period in a position that cramps down on a nerve or vein, restricting blood flow to a body part.
There are many catalysts that can cause paresthesia, the most common of which is temporary nerve or blood vessel compression. While it can be bothersome, it is an extremely common and usually benign occurrence which is most often nothing for which to worry. We know it as a limb “falling asleep,” but the medical term is called paresthesia, a tingling, tickling, or prickling, usually felt in the extremities. Feeling an unmistakable sensation of “pins and needles” in the arms, hands, legs, or feet can be startling.
