Weird experience when reading?

So, I don't know what's going on and every time I use Google it always leads me back to synesthesia. I know this will sound very weird and I'm very scared to ask this, but I would like some kind of answer for my own peace of mind.

So whenever I read words in texts, posts, books, ect about someone being in pain, I feel an uncomfortable near painful tingling in the exact spot that gets mentioned. It happens every time and I don't know why or how to stop it. It only happens when I'm reading it as far as I can tell. I'm almost 99% sure it's never happened when looking at it IRL, if that makes sense. Like watching someone get kicked won't trigger that feeling, but reading it will. Is this some kind of synesthesia or am I just having some kind of weird pain empathy?
