I'd understand you, but maybe add 'really tight' before stocking to emphasise the pain and change 'one' to 'an' to make it sound more natural. So, I feel like I've worn a really tight stocking over my head for an hour Simple ones are My head is about to explode. Arghh. Someone turn out the lights. (particularly good for hangover headaches) My head feels like it's in a vice. Generally something related to squeezing or exploding is good. (The following ones, as Mark points out, are not common but they are good if you want to go for something a bit wacky like you mention later on.) For something with a bit more impact try something like I feel like an ant is making a nest inside my head. I feel like I've got my head stuck between a sumo wrestler and a sharp rock. I feel like my head's been infested by aliens and is about to explode. My head feels like dynamite and the fuse is about to end. My head feels like it's been through a car crusher. or It feels like somebody is using my head for origami, but it doesn't bend that way. Ouch. and I'm sure there are many more. Hope that helps.

Hi Hailey^^ I can understand how Matthew's comments are expressions for headaches, but I wouldn't say they are common. Although, common expressions he mentioned are: My head is about to explode. My head feels like it's in a vice. +1 Amanda +1 maryjane - you can also use throbbing ~ pounding. But I reckon we describe a headache more by severity than symptoms. A couple from me to add to your list: I've got a massive headache. I've got a pretty bad headache. I can understand your stocking scenario, but I would class that more as 'artistic' than common. :P 몸 조심해~~

My head is pounding. I feel like someone is_______ my head over and over again.

We also say "I have a splitting headache"

.. I'll raise you peachy with "a wind of a thousand slaps" (ok I made that one up too) ^^
