Are the aforementioned symptoms accompanying the search for a bride (such as tears when reciting the Quran, burning and numbness in the left leg, fear, and pain in the knee joints) symptoms of magic, and what is their cure?

It is not possible to definitively say that you are enchanted, but you can perform ruqyah (exorcism) on yourself, as it is beneficial, along with relying on Allah, having a good opinion of Him, making abundant supplications, and seeking refuge in Him.

You can also consult a specialized psychiatrist or the consultation section of the website. There is no harm in seeking a trustworthy raqi (exorcist) who adheres to Islamic law.
