Do I need any tests to help diagnose my problem?
Most people do not need tests for this problem, but your doctor or physical therapist might try some tests that apply force to your legs and pelvis to test for the source of pain. If you have pain down your leg or your foot feels weak while walking, your doctor might want you to get an x-ray or MRI.
