Tingling and Numbness
Tingling and numbness is the unusual experience of prickling sensations, often in the hands, feet, arms, and legs. The medical term used for it is paresthesia. Various things can cause these sensations, including sleeping on an arm or sitting cross-legged. Usually, the feeling goes away after a couple of minutes. However, if it persists without apparent cause, it could be a symptom of an existing condition, such as an injury or multiple sclerosis.
Other potential causes of tingling and numbness are animal or insect bites, mercury, toxin exposure, atypically low sodium, vitamin B12, radiation therapy, and specific medications like chemotherapy. Nerve pressure and skin damage are other possible causes. Those with medical conditions like diabetes, migraine, Raynaud’s phenomenon, neuropathy, underactive thyroid, atherosclerosis, and seizure disorders may experience the sensation too.
The reason for the symptom will usually determine the treatment option. To diagnose the problem, doctors typically have tests like a CBC, toxicology screens, electrolytes, thyroid function, and vitamin tests ordered. Some include topical solutions and remedies, supplements, physical therapy, exercising, wearing braces or splints, and dietary changes. Those who begin to feel dizziness, muscle spasms, frequent urination, or rashes are advised to seek immediate medical care.
