I am having ACDF surgery on June 6th and have a big herniated disc at c6/7 and we will be traveling on an airplane to the US VI St. Thomas. I need some advice on what kind of neck pillow I should use for the flight to support my head during travel. I don't want to spend a whole lot of $$$ but I think using something is better than nothing.. Any advice on what works, and what doesn't is welcome!! Thanks in Advance!!
