Respected Hakeem sahib Asslam o alikum! I have a proven tip for, whomever I (dham) blow this he recovered with the Grace of Allah. Blow it after reading it in one hold breath, do thrice. Recite sora Fatiha, Last three verses, and Ayat Tul Kursi, whichever children I blow this Allah Showed His mercy. I did it many times. I am doing it from 7 years it makes my work. (Atah Allah)
