I fell about 5 weeks ago down some stairs and landed on my butt. a lump appeared at the top of by right cheek and a very bad bruise over the entire right side. The bruise went away but the lump is still there and is not getting better. It is still warm to the touch and very tender. If I barely touch it on anything it about brings me to tears. I see alot of people talk about the lump being hard after an incident like this but mine is hard in spots(around the outside) and "squishy" toward the center like theres fluid. I am also experiencing achyness in my lower back and joints( may not be related). Advice?? Should I be concerned?
