Is it better for a Muslim to recite upon themselves, or to go to reciters, especially if the sorcery had been undone then returned again after going to more than one reciter?

It is better for a Muslim to perform ruqyah on themselves, as the Prophet (peace be upon him) used to perform ruqyah on himself. He would blow into his palms, reciting "Qul Huwa Allahu Ahad" (Say: He is Allah, [the] One) and the two Mu'awwidhatayn (Surahs Al-Falaq and An-Nas), then wipe his face and whatever he could reach of his body with them. Performing ruqyah on oneself is more conducive to sincerity. Seeking ruqyah from others is permissible.
