They may use tactile tests to determine nerve function and check for areas of numbness or altered sensation. Imaging tests such as X-rays might be ordered to exclude underlying bone fractures or foreign objects if suspected. In some cases, nerve conduction studies are performed to evaluate nerve function more precisely. A thorough medical history regarding the injury's cause is also important for accurate diagnosis.
