Doctors of eve, I have a question.

I don’t know if there’s a specific group for this, but this is as close as I could find so... when I was in kindergarten I broke my arm. It wasn’t healing correctly and I ended up having to get surgery (I got wires put in my arm). that was 10 years ago. Every now and again the scar tissue build up in my arm will bother me, and make it so I can hardly move my wrist without it hurting. Today it hurts REALLY bad and I don’t know what to do. Also whenever I hit it, it like sends a shock of pain throughout my entire body, and if somebody grabs it too hard, it does the same thing. If anyone knows how to help please do. (I also can’t go to the hospital because I’m only 16 and my dad is one of those “I’ll only take you to the hospital if you’re dying” kind of people)
