Basically I'm ridiculous and somehow I've hit the back of my head about 30 minutes ago, I was putting shopping in the boot and thought the boot door had fully opened but it hadn't and as I lifted my head out, I - with some force - hit the boot door. I have had a massive headache now for whole time. Took paracetamol about 5/10 minutes ago. Am I being a wimp? Is there anything else I can do? Ice pack?
Thanks
