I have suffered with horrible migraines as far back as I remember. Light, sounds, movement, heat, it all makes it worse. I bought this cold cap on a whim, not really expecting much. I immediately found what I had been missing! The coldness, the dark, the compression all work together to help my medication give me relief. If you have migraines, you absolutely need one of these caps! They are a game change for conquering migraines. I recommend 1,000%.
