If one is suffering from a severe headache which cannot be diagnosed, and one does not seem to benefit from any treatment, seat the patient in front of you and ask him to hold his head with both hands.
Recite یَامُجِیْبُ (Ya Mujeebu) in the heart 7 times and give him a strong knock. As soon as he is knocked, he should take his hands away from his head.
Practicing this for a few days will stop the patient from complaining about a headache.
