Mystery Knee Injury??
A few weeks ago i went camping. my friends and i were doing pull ups on a pole to hang lanterns. I hit my left knee cap pretty hard off of it. Later that day, the area was really soft and bruised badly. The area then formed a hard ball, a little smaller than a cherry. It’s been bothering me ever since. My mom wants me to get it looked at today before I start marching band. Any suggestions?
I don’t know what your question is but it sounds to me that you hurt a tendon or a ligament. That’s not good. You might have a knee brace. But the soft spot was it swelling and the hard part was probably the spot you hit it at.
I hurt my knee 2-3 years ago and it was a total mystery. Like, I don’t even know how I hurt it! I ended up TEARING a tendon. I had to go to therapy to help myself bend my knee. IT hurt but I got through it. I just put a heating pad and ice pack on switching it every 10 minutes from heat to ice, etc. to stop the swelling. The bruising sounds pretty bad but then again its going to bruise if you hit it.
Can you please ask a questin because I have no clue wat your asking.
