Oh, I edited the post, but all the content was lost...
 I just went to the hospital, and luckily the doctor said it wasn't a big deal, my nose was really swollen,
 and my forehead doesn't seem to be filled with blood at the moment. And
 after taking the splint off, I feel like I have less cramps and am much better off!!
 I'm really glad.
 But I'm good at tolerating pain, but the tightness and tenderness in question was really serious. Why on earth were those symptoms like that? When I think about it again, I don't think it's just because of the splint. I really don't know if it's because of stress. Anyway
 , thank you all for your concern and comments♡♡ Thanks to you, I got through the two days of hell. I really love you. Stay healthy, everyone♡♡
