I fell on a set of marble stairs three weeks ago and hit my left knee directly on the corner of the step. I immediately saw stars and became very light headed. I also felt nauseous. I went home and iced/elevated my knee. I was unable to bend it nor walk up/down stairs for one week. It was very swollen, bruised, and had a large cut. After a week I gained mobility back in the knee but it still hurts. This past week I noticed that a large lump formed and is very predominate when I bend my knee. What is this? Should I see a professional?
Hi, dear. I have gone through your question. I can understand your concern. You have history of trauma.  You may have some injury to your ligaments or meniscus.  So that hematoma formation occurs and it causes lump.  You should take symptomatic anti-inflammatory plus analgesic Chat Doctor.  You should go for MRI knee to know exactly where you have injury.  Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
