Suggest Treatment For A Bump On The Lower Leg

I received a bump or welt/knot on the side of my leg just below my knee cap about two weeks when skiing. While I intitially didn't realize the injury, once discovered, I immediately iced it, and it went down but i went skiing the next day and have been traveling since with a lot of walking involved.

While it doesnt hurt to walk, after sitting for a prolonged period or standing it on it w/o moving for a long time it can get stiff. It's taking awhile for the lump to subside and again, I am without pain but am wondering how long it can take for this knot and remaining bruising to subside.

Do i need to visit an urgent care facility or is what I am experiencing more of the norm and expected? Thanks
