A sudden tingling sensation overtaking your hands, feet, or face is a fairly common complaint reported by people in the United States. It may be a result of either sleeping for prolonged hours on either of your limbs or sitting in the same position when reading or writing.
Medically termed as paresthesia, a tingling sensation is usually an outcome of trauma or injury to the peripheral nervous system (PNS). The PNS is a component of the nervous system that connects the brain to the various organs of the body through a network of nerve fibers. It transmits information back and forth in the form of nerve impulses or signals.
When a nerve is pinched or compressed, the transfer of signals may be delayed, slowed, or hampered, affecting the brain’s capacity to interpret signals and send back responses. In order to cope with this phenomenon, the brain responds by associating the sensation to numbness and tingling. These are the first symptoms of a nerve injury.
A mild or temporary tingling marked by a “feeling of pins and needles” can be relieved as soon as the pressure on the associated nerve is relieved. In cases of transient paresthesia, usually caused by a mild nerve compression, the symptoms resolve on their own.
Tingling and sensory problems are common in patients suffering from neurological disorders, chronic painful conditions such as fibromyalgia, and other diseases, complicating the diagnosis at times. However, there is partial clarity in cases of facial tingling.
In nearly all facial injuries, the trigeminal nerve is mechanically compressed, stretched, or inflamed. Facial tingling affects the facial skin region as a numb tingling or a skin crawling feeling often coming without pain in the initial stages. If the predominant symptom is facial pain, then the disorder is called trigeminal neuralgia, a relatively well-characterized neurological disorder of the trigeminal nerve. Read more
