Anyone have any recent updates / luck on this? Aside from the latest post (maybe from Dr Rick's office???), there doesn't seem be an update on this for years. Is the shot a scam or real? And if real why is it not more widely used? My neurologist wrote it off as a scam but then again...if it legitimately worked for some why? I did contact the Dr's office and they seem to be short / rude / give no information beyond showing up and paying the $300 so there is reason to be skeptical...
