Pins and Needles: More Than Just a Numb Feeling

Pins and needles, medically termed paresthesia, typically arises from temporary nerve compression, such as prolonged pressure when sitting or sleeping.

While usually resolving upon repositioning, persistent or frequent occurrences warrant attention. Poor circulation, potentially linked to conditions like varicose veins or arterial buildup, can cause these sensations, often accompanied by other circulatory symptoms.

Diabetes is a significant cause, where high blood sugar levels can damage nerves, particularly in the feet and legs. Nutritional deficiencies, notably in vitamin B12, folate, or B6, can also impair nerve function.

Raynaud's disease, affecting millions in the UK, causes reduced blood flow to extremities in cold conditions. Carpal tunnel syndrome, common in the UK, involves nerve compression in the wrist due to repetitive movements or conditions like diabetes and arthritis.

Crucially, sudden onset of pins and needles, particularly on one side of the body and accompanied by other neurological signs like facial drooping or speech difficulty, could indicate a stroke, necessitating immediate emergency medical help.
