Chronic Migraine is a condition caused by imbalances in the neurochemicals in your brain. Having chronic migraines can be debilitating and can put your daily tasks on hold. Botox is widely known for aesthetic uses, but is also FDA-approved to relieve migraine headaches. Small doses of botox is injected into the scalp to relax tense muscles and prevent the neurochemicals from causing a migraine. Botox has been proven countless times to be a continuously effective solution for those suffering from chronic migraines.
