Why am I having pain in the back of my head on the right side

[Brusier21]

I am trying to figure out what could be causing the pain in the back of my head on the right side I have not injured my neck that I know of

This is hard to say.  That you don't have a specific injury to point to for this, it is a little trickier.  But we can have injury or break down over time too.  WE have all sorts of muscles  attached on our head.  Right behind our ear there are several.  I have a chronic neck injury from a car accident and when the muscles below my ear tense up, it pulls on the back of my head on that side.  Gives me a headache.  For me, ibuprofen, massage and head stretch/neck stretch really helps.  I can also simply sleep in the wrong position and end up with a stiff area on my neck or head.  Sigh.  So, try some stretching-- drop your chin to chest and tilt head one way slowly, then the other.  Hold chin at regular level and let head slowly stretch one way and then the next.  Point chin up and turn head one way and then the other.  An ice pack also really helps with these things.  good luck
