            Cooling for migraine. As a migraine sufferer, I've tried countless products over the years. This is one that truly works. I have an ice pack for my head, but while travelling or at work, it's not always available. These patches are a fantastic alternative for a soothing cooling effect. I apply them horizontally across my forehead and vertically on my neck/spine. The cooling sensation lasts several hours. I recommend this product for migraines.
