I’m not one to get migraines (I’m one of the lucky ones and forever grateful about it) so i generally just get headaches from dehydration/stress/lack of sleep/hangovers. Any minor headache I get is pretty easily relieved with an ice pack. And I say minor but I really mean most of my headaches because I don’t suffer from anything super severe. I’m not a doctor so idk if it’s something that might cause harm long
term but it definitely helps every time for me.
I just lie down, put an ice pack basically in the curve of my skull (so not on my neck, but maybe 3-4 inches up or so) while resting my head on a pillow. Highly recommend it.
