Hello. My friend has osteoarthritis and that’s how he describes it: “I was diagnosed with osteoarthritis in my lower right neck (some bone was chipped away).  It happened as the result of a car accident in which my car was struck from another car behind me at about 10-15 mph while I was slowing down at a stop light.  That was in 2001. I have had constant discomfort in my neck and very slight numbness in most of the right side of my body as a result.  Then the same kind of accident happened three weeks ago - this time the impact was slightly less, but it caused more soreness in my neck. ” I would appreciate any information on the use of BVT in similar cases. Many thanks in advance.
