A few weeks ago I fell and hit my knee on some concrete. It bled and swole. Then next day I couldn’t straighten it out to even walk, I literally crawled out of my room, down the stairs, and found a knee brace. I had to go to work that day so I have to endure the pain. Well 2 weeks later I get a sinus infection. While at the doctor I ask him to check out my knee because it has vein like bumps on it and it still hurts to walk or bend it. He said I’m fine and that it’s all in my head. Today makes 1 month since it happened and my knee still hurts, it feels broken, the bumps have gotten worse, and I can’t bend it to even pick something up. I have a VERY high pain tolerance and this has been the worst thing I have ever felt in my life. Please help me.
