THIS is why you don’t cosplay with wigs/crowns/hats/etc that are waaaay too tight.
Don’t try and tough it out, because bruises will happen. If you feel uncomfortable, TAKE IT OFF. SERIOUSLY.
This was the result if wearing a wig and a Sailor Venus tiara that were both very tight. The tightness made me feel physically sick, but I didn’t want to seem weak, so I kept it on the whole day (10 plus hours)
Don’t try and suck it up and ignore it, because you WILL injure yourself.
