--with doctors in the Kansas/Missouri area, and don't know how far you'd be willing to travel; perhaps someone on the Spinal Disorders forum would know more.

I'm not familiar with a test called an MRG--usually that stands for microradiography, which is a lab technique--is the doctor possibly referring to a nerve conduction study (NCV) or electromyography (EMG)?

I think physical therapy may well be a good idea, though it may take some time to find one who is familiar with spinal problems and with techniques, such as gentle traction, designed to help create some more foraminal space.
