My RSD began in the neck/head area most likely due either to disc herniations, a fall from a tree or neck muscle strains. I guess I'll never know but all of my symptoms began there and as my Ketamine treatment continues, that area has been the most resistant.

The RSD spread through my entire left side and I'm happy to say the ketamine has almost completely reduced it to that area now and reduced the pain tremendously.

Do you have any symptoms that concern you at this point and make you think it's spreading there?

Migraines became a huge problem for me along with neck/ shoulder pain and intolerance to any light in my left. eye.
I did also have burning and eye pain in both eyes on a nightly basis despite no eye problems.
