I have a lump on my knee ,I have had it about 5 weeks at first it was quite squashy and painless ,but now it as gone hard and my knee is starting to ache and I can't kneel on it .its about the size of half a golf ball :confused:

Without knowing more detail as to what transpired before the lump occurred or if it just appeared one can only guess as to what is going on. I would seek medical treatment immediately due to the symptoms getting progressively worse.
