Boston Eye and Ear diagnosed my wife with VM a year ago after several hours of testing, so we felt we were on the right track. The oto-neurologist there did feel the VM could be impacting the trigeminal nerve system also, which could account for my wife's odd tactile sensations. Other neurologist however have questioned whether this is actually what's going on, so we are not certain she is on the right track. Boston is too far away for us, so she is now seeing new primary care and specialists at Dartmouth Hitchcock Medical Center (NH) and they have been great. Multiple disciplines are involved and they are taking her symptoms seriously. Her symptoms are relentless 24/7, so we desperate for some relief for her after 2 years of suffering.
@jenniferhunter has suggested resources to us regarding interaction of vestibular and trigeminal nerve systems that have been informative.
