Ali - is it possible for you to leave the UK and go to another European country for treatment? For instance, Germany has ketamine. They likely offer the multi day long infusions as well as the comas. Perhaps you can find Lidocaine infusions in a nearby country . It seems that you are pretty limited in your choices right now, and your suffering has become more severe since your arm injury last month.

The family of a boy from my state (in the US) that needed financial help getting to Germany for the K coma held numerous fundraisers and collected money through a website.
