what is causing these pains?

my friend has these small little bumps on the left side of his head and he's been having headaches and pains all through his head everyday. he's always complaining that it hurts too. the bumps went down but he still seems to have headaches and shooting pains all the time and his neck has been hurting him all over and he feels like **** all the time.
he does not know what it is either. there just little bumps that appeared and is causing him to have headaches and causing his neck to hurt all around all the time.
