Underlying conditions discussion: It more frequently occurs as a symptom of more widespread neurological disease or traumatic nerve damage. Paresthesia can be caused by disorders affecting the central nervous system, such as stroke, transient ischemic attack, multiple sclerosis, transverse myelitis, and encephalitis. A tumor or vascular lesion such as an arteriovenous malformation pressed up against the brain or spinal cord can also cause paresthesia. A wide range of conditions including diabetes, hypothyroidism, vitamin B12 deficiencies, alcoholism, heavy metal poisoning (lead, arsenic, and other metals), and nerve entrapment syndromes, such as carpal tunnel syndrome, can also damage peripheral nerves (peripheral neuropathy) and cause paresthesia. Connective tissue disorders such as rheumatoid arthritis or systemic lupus erythematosus also can cause peripheral neuropathy and lead to paresthesia. Paresthesia caused by peripheral neuropathy may be accompanied by pain. 1
