Migraine is not just a headache. It is a neurological exploding party in the brain, that pain happens to be invited to.
Typically, episodes affect one half of the head, are pulsating in nature, and last from a few hours to days. Associated symptoms may include nausea, vomiting, and other symptoms such as sensitivity to light, sound, or smell.
Migraine is believed to be due to a mixture of environmental and genetic factors. About two-thirds of cases run in families. The underlying mechanisms are not fully known. They are, however, believed to involve the nerves and blood vessels of the brain.
Initial recommended treatment is with simple pain medication such as ibuprofen and paracetamol for the headache, medication for the nausea, and the avoidance of triggers. Specific medications may be used as preventive treatment, in those for whom simple pain medications are not effective.
Marijuana has natural compounds called cannabinoids. When used they circulate in the blood and work on pain receptors to calm down pain signals and control or abort Migraines.
THC and CBD in particular have proven to be useful to manage Migraines.

However, the evidence for migraine sufferers suggests that medicinal cannabis may help reduce how often they occur, as well as how bad they are when they happen, though it is unlikely to get rid of migraines entirely.
