I have tried painkillers, didn't work. I have tried having a nap, didn't work. I have tried caffeine which has helped me in the past when I had a headache, didn't work. This headache is agonising, I need to get some work done by tomorrow and if this headache continues I wont be able to do it. Has anyone got any ideas on how to cure headaches? I have headaches quite often but not usually as bad as this.
