Carpal tunnel syndrome is the standard diagnosis when patients show up with numbness, tingling, or weakness in the thumb, index, and middle fingers. The classic explanation is that the median nerve is being squeezed at the wrist, where it passes through a narrow passage called the carpal tunnel. That can absolutely be the case, and surgical release at the wrist is the conventional fix.

Here is what often gets missed: the median nerve does not start at the wrist. It starts in the cervical spine and travels through the shoulder, the elbow, and the forearm before reaching the hand. The nerve can be compressed at any point along that path, and the symptoms feel the same regardless of where the squeeze is happening. Patients who have had wrist surgery and still feel the same numbness usually had the problem somewhere else.

Dr. Lena Hartwell examines the entire nerve pathway, not just the wrist. The cervical spine, the shoulder, the elbow, and the wrist all get checked. If the source is in the neck, a specific adjustment to the involved cervical vertebra often produces fast change in the hand symptoms. If the wrist is the actual source, the care plan reflects that. The point is to identify where the nerve is actually being compressed before committing to any single course. Many patients who were told they needed surgery have found relief through this approach. Others learn that surgery is the right call for their case, and they go in with a clearer picture.
