The Headache Ice Pillow combines cervical support and cold therapy to help relieve headaches, migraines, neck pain, muscle soreness, and tension headaches. Also ideal for stiff necks, sprains, strains, and symptoms associated with whiplash injuries. Use cold therapy to help reduce inflammation and headaches; use heat therapy to help relax muscles. The unique horseshoe shape of this pillow provides support while sitting or lying down. For resting or sleeping in a sitting position, the 100% virgin polyester fiber fill cervical lobe supports the neck while the two side lobes gently cradle the head for comfort. The compact size is ideal for travel or home. Convenient pocket for removable hot/cold pack. Use this pillow either with or without the 6" x 10" soft comfort flexible hot/cold pack. The pack's exterior is made of a proprietary blend of synthetic fibers and organic plant materials. The Soft Comfort CorPaks contain more nontoxic, biodegradable fill than traditional packs to retain cold and heat longer. Conveniently store packs in the freezer for a minimum of 1 hour prior to use for cold therapy the moment you need it! For heat therapy, simply heat the pack in a microwave according to the heating instructions printed on the pack. The pack will maintain therapeutic temperature for 20 minutes.
