Suggest Treatment For Pain When Suffering From Chiari Malformation

Hello, A dear friend of mine just found out that her three year old son has Chiari Malformation. I personally have neck issues from injuries and my Chiropractor set me up with a tubular pillow that I place below my neck when laying on my back. It has made such a difference for the better. Is there a pillow for a small child who has Chiari Malformation that could possibly relief some pain? Thank you. . . Theresa
