Has anyone ever been advised to use a Pointer Plus acu-point to manage symptoms?

Has anyone ever been advised to use a Pointer Plus acu-point to manage symptoms? I have a rigid big toe, which is likely the cause of my symptoms (metatarsalgia and sesamoiditis...still trying to diagnose). My osteopath suggested this device so I could try to manage on my own rather than paying $190 to see him every couple of weeks. He also showed me how to manipulate my big toe to keep it from getting locked up. He's not typically someone that suggests stuff like this.
