A feeling of pins and needles or tingling in your hands and feet is a problem that bothers many people. This is not just numbness, but can also be a sign of some changes in the body. The main causes are:
Vitamin Deficiency: Vitamins B12, B6, and E are essential for nerve health. Vitamin B12 deficiency in particular can cause chronic tingling and weakness in the hands and feet. This is more common in vegetarians and those with digestive problems.
Diabetic Neuropathy: In diabetics, uncontrolled blood sugar levels damage the nerves. This first appears in the feet and then in the hands as numbness and tingling.
Nerve Compression: Disc Prolapse (disc prolapse) can cause numbness in the hands or feet when pressure is placed on the nerves. Similarly, compression of the nerve in the wrist (Carpal Tunnel Syndrome) can cause numbness in the fingers.
Reduced blood flow: Impaired blood flow to the hands and feet can cause numbness. If the hands and feet are kept in the same position for a long time while sitting or sleeping, blood flow decreases and numbness occurs.
Thyroid problems: Low levels of thyroid hormone (Hypothyroidism) can cause fluid to accumulate in the body, which can put pressure on the nerves and cause numbness.
