Hi Mari: When did you have your injections? I can't seem to get to Dr. Thomas Vangsness with USC .The phone numbers don't work and calling USC directly has been frustrating. I would gladly drive from San Diego to LA to see him. Or maybe some one knows a resource in San Diego. I found one recommended Dr near here. His price is $650. per joint + the initial visit is $240. I'm so grateful for all of the information that comes on this chat site.
