[|Human|] Hi, Over 3 weeks ago I was playing ice hockey and took a shot off of my shin pads, which left a lump on my tibia, the bruising has gone but i still have a lump (half the size of golf ball) that is sore to the touch. What, if anything, should I do about it? I have exercised on it since so it is not broken.
[|AI|]  Dear user, When you get a hard enough blow, it causes blood to collect under the skin if there is no wound Hematoma, as we call it. That usually takes 4-6 weeks to go away, even after the redness is gone. It will usually change its color from red to purplish to green and yellow before it completely fades away. If this continues to decrease in size, you don't really need to do anything. Just take painkillers and cold compressors as needed. If it becomes redder, or the swelling becomes more painful or increases in size, there are chances it has got infection. In that case you'll have to go your doctor to get it checked. In rare cases it needs operation to clean. There are very minimal chances that this kind of lumps persist after a few weeks, if it does persist though, you might need an x-ray to rule out small fracture, or any other kind of skin lump which you only happened to notice after the injury. Do write back if you need more help. Thanks
