All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.
We pray to Allaah, The Exalted, for your wellness and safety against all types of affliction. We advise you to keep patient and supplicate Allaah to bless you with recovery. You should also have good thoughts about your Lord. Verily, Allaah, The Exalted, is as His slave believes He is. You should know that Allaah, The Exalted, is able to do all things and there is nothing that is difficult for Him.
You are advised to consult doctors and specialists and recite the Islamic Ruqyah regularly, for it is beneficial by the permission of Allaah. Please refer to Fataawa 88705 and 91355 about treating epilepsy with Ruqyah. Please also refer to Fatwa 83577 about the wisdom behind afflictions and the virtue of patience.
As for wearing a necklace or bracelet, if such a necklace or bracelet is worn for beautification purposes, it is considered imitation of women (which is forbidden in Islam). However, there is nothing wrong with wearing medical necklaces or bracelets that are worn for medical reasons and are not of the type mentioned above.
Allaah Knows best.
