I feel that anything withen reason that will help your chronic pain is worth a try. I enjoy my natural treatments for my chronic back pain.
There are different theories regarding the use of cannibus in chronic pain. It is possible that it might provide some benefits, The bigger issue is whether you will be able to receive the medical authorization under state laws and if the federal law does not specifically identify use of cannibas as illegal.
It would be best to discuss the options with your doctor and proceed from there.
Hope you find resolution soon ---
