Ketamine is one of the many treatments for CRPS. These days, people are being diagnosed much more quickly than they were back in the 1990's. The advantage of earlier diagnosis is that treatment can be started more quickly. I couple of months ago, someone joined my Newly Diagnosed Facebook group. She was diagnosed two weeks after symptoms started as compared to my 2 years after the onset of symptoms. Christine did her homework and decided that ketamine gave her the best chance of being able to go back to work. I interviewed her for my YouTube Channel before she left to get a loading dose of ketamine and again after she completed her loading dose of ketamine. Here is a link to the show. https://youtu.be/e4ydfxQQrEw
