I fell and bumped my head on a pavement one week ago, I had severe bruising to the left side of my face & upper body, I went to A&E. One week later my arm/ hand and shoulder are better and the bruising on my eye and face is getting better but I still have a substantial swollen lump on the left side of my forehead which is not reducing in size at all. It is semi soft to touch and quite painful. Should I ask to get it x rayed?
