I have buldging disks and thoratic outlet syndrome in my neck. I am in constant pain with this problem. I use to be a flight attendant and had to be extremely physical at my job. I used thermacare air activated neck wrap when I worked International flights. I was on the plane for eight hours most of the time, and this product really helped with my pain. I also had no trouble going through security with it, which is a big plus these days. I would definately recommend this product to anyone that needs a on-the-go neck pain reliever! It was also a big plus that I could keep it concealed under my uniform...
