Does Medical Marijuana Help In Treating Chiari Malformation?

I have been having terrible headaches with neck and shoulder pain and was recently diagnosed with chiari malformation 1. Doctors have tried many different medications to help with pain. I have had bad reactions to some and the others haven t worked at all. My doctor has run out of ideas and wanted to put me on antidepressants to see if that would help but i declined because i don t suffer from depression. He has now decided to go with trying vitamins to get it under control but of course the vitamins are causing me problems with nausea. I was wondering if medical marijuana could help me considering I have so many problems with regular medications. I m not sure if it is even a possibility in my state but I would like to know anyway. Thank you
