your problem seems different than what i had. i had migraine headaches for 10 years. the doctor gave me imatrex and asprin. i would get in a fetal prosition with my head pounding, eyes hurt, feel nausea. if i get it at 6pm it wont go away til the next day.
it was due to stress, b/c when i lost my job and boyfriend the headaches went away.
if they dont know what you have does any kind of medication "strong pain pills work"
doctors dont know everything, i can tell you many stories where i had to solve my own problem.
have you considered seeing a dentist?
there has to be some strong pain pills your doctor can prescribe to you until you figure out what's wrong.
no one should live with pain.
