[|Human|] Hello,This afternoon, a hard painful lump about the size of a quarter appeared above my right knee cap, then turned to bruising. It is not raised and hard anymore, but still bruised and tender. I may have bumped into something right before, but dont remember because if I did, it wasnt hard and this appeared suddenly. Any idea if it is something that should be checked out? Thanks!
[|AI|]  Hi there, A painful lump on above the knee is most likely a hematoma (bruising and blood collection under the skin). I would apply heat and take ibuprofen (no more than 800 mg every 8 hours) to help relieve the symptoms. If it doesn't resolve, an ultrasound can help to identify the mass.  It is a quick and non-invasive test. I'd give it about a week and if it hasn't gotten better, you can see your primary care doctor or an urgent care doctor who can order an ultrasound for you. I hope this is helpful. Please feel free to contact me if you have any further questions.
