Review (5/5): immediate relief for fever and headache
We use these for fevers and migraines in our house. The very best thing about them is that they provide immediate relief to a sick child. Medicine takes awhile to work but these provide instant comfort. I put them on the back of my neck when I get a migraine and it feels wonderful. If the cool sensation wears off too soon, we have put the patch in the freezer for a few minutes to cool it down and "re-charge" it. I'm so glad these are on Amazon because I have driven to every pharmacy in the area and can't find them on any shelves.
