Today, I cut the back of my hand with a knife. The scar is only two centimeters. I cut it three times. I feel particularly weak now. I didn't bleed when I cut it, but I can still see the scar. Yes
Yours is completely psychological, medically called unconditioned reflex (there are two kinds of conditioned reflex, and words with non-words are congenital). 16 years ago, I did the same stupid thing. I drank a lot at that time, and I was still a minor. The incision is too deep, the fascia is broken, and the tendons of the index finger and middle finger are also seriously damaged, which is close to breaking. However, due to the timely remedy, I was close to the county hospital and sewed 16 stitches. At present, there is nothing wrong with the basic function, except that there is 1 obvious scar on the back of the hand.
