If you are experiencing numbness and tingling in your fingers on a consistent basis, you should have this checked out with your care provider. Your care provider will inquire about your history, perform a physical examination, and potentially order additional testing to determine whether your symptoms are likely due to CTS. Additional testing may include electrodiagnostic testing (also called a “nerve test”) to check the function of the median nerve and other nerves or ultrasound imaging to directly visualize nerve swelling. Some studies indicate that earlier recognition and treatment of CTS may be more likely to result in improvement and avoidance of surgery.
