What Is Carpal Tunnel Syndrome?
What is carpal tunnel syndrome? Carpal tunnel syndrome is the name for a group of problems that includes numbness, tingling, weakness, or pain in your wrist or hand . It's a very common condition that happens when a nerve in your wrist becomes squeezed. The carpal tunnel is a narrow opening between the bones in your wrist and the ligament that holds them together. A nerve, called the median nerve, runs from your lower arm through the carpal tunnel and into your hand. This nerve provides feeling to your thumb and first three fingers. It also helps you move your thumb. Tendons also run from your lower arm, through the carpal tunnel, and into your hand.
Pathophysiology, Underlying Causes & Clinical Presentation
Biological expression of Carpal Tunnel Syndrome (G56.00, Chronic Pain & Nerves) reflects impaired descending inhibitory in Carpal Tunnel Syndrome (G56.00: pain modulation). Cross-referenced with NIH MeSH (Carpal Tunnel Syndrome), longitudinal control is benchmarked via hs-CRP & ESR in Carpal Tunnel Syndrome (G56.00: Inflammatory Check).
Common Symptoms & Clinical Signs
- • Injury to your wrist that causes swelling, such as a sprain or broken bone
- • Health conditions that can affect your nerves , joints , or other parts of your wrist, for example: • Diabetes
- • Presentation of Carpal Tunnel Syndrome (G56.00): localized nerve entrapment in Carpal Tunnel Syndrome (G56.00: numbness or radiating)
- • Secondary Carpal Tunnel Syndrome clinical sign: burning, electric-shock, or in Carpal Tunnel Syndrome (G56.00: pins-and-needles pain in)
