My iPhone charger has been electrocuting me?

Long story short my mom came in my room and had her hand on my arm and said she felt like electricity running through me like she would feel a humming on my arms. I thought she was crazy. But after a few minutes we realized it was my phone in my hand plugged into the wall! I wondered why I couldn't sleep or breathe and my heart was racing. I'm obviously not going to use this charger but I've been using it and sleeping with it like it under me plugged in for a while. Has this done any damage? I mean I have a million health problems always. But anything in particular I should look out for?!

Just stop using that charger.

You didn't do anything to damage your health.
