What is the treatment for brain numbness, severe fear, physical pain, insomnia, and recurring headaches, and is this considered witchcraft or envy?

Allah tests His servant to expiate his sins, to make him remember his Lord and prepare for meeting Him, to reflect on his own state, to mend his affairs, and to become upright in obeying his Lord's command. As Allah Almighty says: "Corruption has appeared on land and sea by what the hands of people have earned, so that He may let them taste some of what they have done—perhaps they will return." (Ar-Rum: 41). And He Almighty says: "And We tested them with good [times] and bad [times] that perhaps they would return." (Al-A'raf: 168). And He, glorified be He, says: "And We seized them with punishment that perhaps they would return." (Az-Zukhruf: 48). And He, عز وجل, says: "And We will surely let them taste some of the lesser punishment before the greater punishment that perhaps they will return." (As-Sajdah: 21).

Increase in supplicating to Allah and seeking refuge in Him, and present yourself to ruqya practitioners who adhere to the methodology of Ahl as-Sunnah (definition) wal-Jama'ah. Beware of charlatans.
