I also suffer from such symptoms at some times as well! But I know I don’t have any Sihr!

This does not necessarily mean you have been affected by sihr, it might be a medical condition. You check with a medical doctor to be on the safe side.

You can also perform ruqyah on yourself. Here is how: https://www.assimalhakeem.net/what-is-ruqyah-and-how-one-should-do-it/

I’m 50% sure I have sihr because I’ve self checked the symptoms. For the last couple of days my eyes have been so heavy when I wake up and during the day/evening. There’s times when my eyes are blurry? What should I do , I’m really scared and there’s no raqi close to where I live . May Allah cure me in Sha Allah
