Tingling or numbness in the hand or arm is a sign of nerve impingement, and finding a solution requires differentiating between a local origin, i. e. in the arm, wrist, or hand, or an impingement happening further away, perhaps in the neck or shoulder region.
The patient’s presentation, orthopedic tests, and careful assessment of the neck and involved upper extremity will reveal the source of the the problem.
In some instances, there is more than one site of impingement, e.g., symptoms in the hand may be due to a “double crush”—-impingement in both the new and the wrist.
