My sister is got into a car accident two years ago and has suffered re-occuring chronic migranes at least 3 to 4 times a week since then. She was diagnosed with post-concussion syndrome and none of her medications do anything to alleviate her pain. She was using botox for a while, but now that no longer helps with the migraines. We were discussing possibly alternate treatments such medical marijuana and based on what I was reading, the results seems to contradict each other. I am wondering if she would be putting herself in danger or exacerbating her condition by using marijuana to help manage her pain.
