Having breast surgery changes the balance of weight on your chest muscles. Until you heal and your body adjusts, you might like to use a crest-shaped pillow to support your breast or your reconstruction. You can also use this pillow to provide comfort to any underarm incisions. 
After my surgery, I carried my pillow around and slept with it for nearly a year.  I don't remember where it came from, but I know it was a Godsend and it helped tremendously. This pillow may become your constant companion.
Made with soft, cuddle fleece and filled with fluffy polyfill. Comes with a matching cover that has a strap to use for carrying over your shoulder.
