What Does A Lump On Elbow Indicate?

For a little over 3 weeks, I have been having a sort of elbow lump- there was some redness around, a bit of swelling and not much pain. Even now the lump is protruding and looks odd -theres no pain but looks ugly I used to get gout attacks on my toe and knees upto six months ago but they have subsided- I have been using allopurinol and colchicine I have been advised by the doctor to continue using allopurinol one tab a day and if there is pain to have colchicine Is there any other way of getting rid of the elbow lump, my doctor is not very responsive Thanks for your advise and help Ash
