Bismillah Ir-Rehman Ir-Raheem Assalam-Alaikum: May Allah guide you, me, and all of us to the Straight Path. If you or anyone is interested in self-ruqyah made according to Quran and Sunnah and ahadith, then they should buy Sword Against Black Magic & Evil Magicians by Wahid Abdussalam Bali. I believe the books answers these types of and other similar questions Insha-Allah and enables those so afflicted to find a cure. I highly, highly recommend it. And Allah and His Prophet know best. If I have said anything that is good and true, it is from Allah, and anything other than that is my own mistake.
