If I could cure one disease it would be HEADACHES!!!! They are so annoying and they can sometimes be painful. Some of the facts are: it us actually the brain that is telling you the other body parts hurt and that is what causes pain, the brain cant feel pain, the usual headache is when the blood vessels in your neck swell, it is also caused by stretching your neck mussels to much, and caffeine can make you have headaches.There is no medicine cure but sleep helps.
