I have horrible migraines and tension headaches. I've been good about working on my posture while sitting and practicing yoga a couple days a week to help relieve some tension in my shoulders, so I thought I'd give this a try.
It does work to reduce the tension and when I feel a headache coming on, I try to use this first before using medication. The only reason I gave it four stars was because it looks and feels a lot cheaper than pictured. However, once you find the right position for you, it does work. I recommend it to anyone wanting to try something to help ease shoulder and neck tension.
