Tingling in Hands
GeneralMultiple sclerosis. TIA (mini-stroke). Guillain-Barré syndrome. Peripheral neuropathy from cancer.
You slept on your arm or kept your wrist bent. Carpal tunnel syndrome (very common — pressure on the median nerve from repetitive hand use). B12 deficiency (especially in older adults and vegans). Poor circulation from sitting awkwardly. Anxiety.
🧠 The full picture
Waking up with a numb hand is usually positional — you compressed a nerve. Carpal tunnel affects 1-5% of the general population. B12 deficiency causing tingling is common and completely fixable with supplementation. Neurological causes exist but almost always come with other symptoms.
