Please look at the slight itch in the skin at the tip of my nose!!! ㅠㅠ Trembling phenomenon

Since yesterday, I've been feeling like there's mucus at the tip of my nose, so I keep peeking at my nose, but there's no nose, but I keep getting that feeling at the tip of my nose . I've set up the pillar of my nose as a septum, but when I touch it, there's something particularly hard on one side. From then on, every five seconds, there is a slight vibration of the skin in the area where the hard thing is being touched. I keep getting a slight tingling sensation, and it feels like it's constantly trembling... I looked it up and found that there are a few people who have recently had surgery. You were there? But it's been a long time since I had surgery ㅠㅠㅠㅠ For your information, it's been over a year since I had surgery ㅠㅠㅠ It's not painful or anything, but I'm worried about my skin shaking. Does anyone have that!!!!!!!!! Or why are you doing this? ㅠㅠㅠㅠㅠㅠㅠㅠㅠ
