question: I have a lump on my head, resulting from an accident that happened a month ago.  My black eye and cuts have healed, but the lump is still there.  I went to the emergency room at the time of the injury, and I was told that the injuries should resolve.  I followed up with an urgent care physician a week ago.  She said the lump appeared to her alot like a cyst (but it was not there before running into metal street sign.)  She advised to get a sonogram.  The lump is located on my forehead above the eye.  It doesn't really hurt.  But I do have some headaches -- not severe.  Could I be referred to a doctor for a sonogram regarding this?
