I did something to my wrist a few days ago and now every evening it starts hurting and my hand goes a bit numb and weird. I wanted to know what to do so I used a symptom checker on my symptoms.
Every single item was some version of a nerve problem. I suppose the lesser ones like carpal tunnel syndrome are possible but it's useless for me to worry about that now. I have exams for goodness sake! I definitely shouldn't waste time googling stuff. And it hasn't gotten me any closer to what's actually wrong with my wrist, there's just a lot of maybes.
Moral of the story: Don't google your own symptoms. It's always a bad idea.
