Have you contacted the TNA support group in Florida?? They go by the Facial Pain Asociation now,,but they usually keep postings on every group they know about,,,can't hurt....
I had an MVD an although for me it did not work I am still very Pro having them if you are the right candidate,, sounds like they think they see something so you probably are.
Although I have a high tolerance for pain,,the first night was bad but I was up and walking the next day and have had back surgeries that hurt more,,,you'll be fine
Keep us posted on your journey,, we are with you
