[Square Jaw] 5-year review of square jaw behind the ear

I had a square chin behind my ear about 5 years ago, and there have been no problems at all and I am living with complete satisfaction. What if there are some side effects? I don't know if my body remembers it, but when I get into a dangerous situation (like tripping on a rock and almost falling), the nerves in my jaw start to tingle... Just like when I ate something sour. Anyway, I was a student at the time and my recovery was free, but I'm regretting doing it somewhere else too. Now again. I'm looking into it haha
