Numbness and tingling conditions are conditions that can affect people of all ages. Most commonly, numbness or tingling results from underlying nerve compression conditions. Other times, blood flow is restricted to the affected area for a variety of medical reasons.
Paresthesia — the pins and needles feeling we get when our foot falls asleep — is the most common type of numbness and tingling. In isolated incidents, such as falling asleep on your arm and waking up to it numb, paresthesia is normal.
However, if paresthesia occurs regularly without obvious explanations, or if it happens to last more than a few minutes, it can be a symptom of a serious underlying condition. These conditions can include a herniated disc, nerve trauma, inflammation, vitamin deficiencies, multiple sclerosis, toxins and more.
Dysesthesia is another condition related to feeling numbness or tingling, although it is much rarer than paresthesia. Sufferers can have extreme nervous system reactions to normal stimuli, such as feeling like your hand is burning when you rest it on a flat surface.
