What could cause whole body numbness and tingling simultaneously?

When you feel numbness and tingling all over your body, it means your nerves are sending mixed-up signals. One reason for this is peripheral neuropathy, which can be seen in people with diabetes and liver cirrhosis. In cirrhosis, the liver's problems may affect the blood and chemicals that help nerves work correctly. Some autoimmune conditions, like Behçet's disease, can also cause nerve problems, making you feel numb and tingly. Another possible cause is Sneddon's syndrome, a rare condition where blood flow and small blood vessels are affected, sometimes leading to widespread neuropathic pain. In other cases, a stroke—especially in areas like the pons in the brain—might lead to unusual sensations. Although strokes usually affect one side of the body, they can sometimes cause mixed sensations that seem to spread.
