Bruised hard lump on right side of knee cap (revised 2nd post)

[JimsFireAngel]

I have a hard (boney) bruised lump on the upper right part of my knee cap.  It hurts to touch it and put pressure on it when I am walking.  It is also swelled (kind of feels like there is fluid in it).  I also feel grinding at the top of my knee when I move it and there it pops on the left side.  Almost two weeks ago I fell and skinned the same knee pretty badly.  The part that got skinned is healing nicely but I don't know what this lump is.  Any ideas on what this could be?  And is it something I should go see my doctor about?

Thank you for you help.  I wasn't sure if it was something I should really worry about or not.  I will call and make an appointment with my doctor.  Again, thank you for your time!

This lump would be collection of fluid or blood due to the injury and you have to continue taking anti inflammatory drugs/pain killers. You should visit an orthopaedician to assess the damage you have done. Take Care!
