Numbness

A partial or total loss of sensibility to tactile, pain, or temperature stimuli in a body region. Possible causes are nerve compression (posture, carpal tunnel syndrome, spinal disc herniation, spinal stenosis), peripheral neuropathy (diabetes, hypothyroidism, chronic kidney disease, vitamin deficiency (B₁₂, B₆, folate), arterial insufficiency (Raynaud's phenomenon, peripheral artery disease), or neurological disease (multiple sclerosis, stroke, transient ischemic attack).
