Thanks for writing in. The knees are the most commonly injured part of the body. The largest joint, the knee is used for everything from standing up, sitting, to walking, running, etc. It's a weight-bearing joint that straightens, bends, twists and rotates. All this motion increases your risk of acute or overuse knee injuries.
As you already have a history of trauma there is a chance of ligament injury or meniscal tear or tendinitis. There is less chance of any fractures as this would have deformed the joint, causing swelling, warmth over the joint and redness etc.
In ligament injury there is sharp pain, which is usually at rest. Where as in meniscal tear there is a popping sensation upon activity with the knee. In tendinitis there is pain always.
It would be better to see a orthopaedician, to confirm diagnosis and take treatment. As any injury if not treated can lead to long complications.
Fell hard on left knee. It became bruised in color and pain, numbness, warm feeling, and burning got worse and worse. The injured area is at the very top of the knee leaving like a crease at the top and across from side to side. It was not in the meniscus area (as I know where that pain radiates since I toreit several years ago and had sursery on it). This does not feel like what I'm I felt previously. At one point I felt something (like a pulling just under the knee to the top of the knee. That no longer hurts.. The burning, hurting, sensitive sensation with like a tiny balloon filled with water from mid knee up has been bothering me for like 4 weeks now. Two days after the initial fall it got injured again when I was pushed into a bus landing on same knee because people can't wait until there turn. So this second injury only made matters worse. The burning, when the knee is bent, like when your sitting in a chair burns so bad my eyes starts to tear. I think you got the idea. Please tell me what the injury is and what is injured within the knee up towards thigh but Not that far up. Please advise.
