Hi ttchica78,
I wish I could say this were true, but migraine is a genetic neurological disorder which is thought to be caused by overactive neurons in our brains and genetics.
Candida overgrowth however may be a migraine trigger for you. Any time our body experiences undue stress, for example if we have a cold or virus, an attack may occur. Example would be if we have issues with our thyroid, or have the flu these things may trigger a migraine attack. We have information in this link that may help: https://migraine.com/blog/migraines-have-triggers/.
Have you by any chance kept a detailed migraine diary recently? This may be a good idea as our migraine patterns and triggers change over time. Take a look at this information on migraine diary basics: https://migraine.com/blog/keeping-migraine-diary-basics/.
I hope this helps,
Nancy
