I don't know what it is or how to treat it:
It started 8 months ago when I felt a sudden acute pain in my left knee as I was running on the treadmill. I had to limp home. That healed on its own but ever since I've had this strange tingling/sensation there. The feeling has come and gone quite often ever since, but almost always shows up when I jog. I also get it randomly while sitting or laying down as well. Ice doesn't make it go away.
It's a strange, not quite painful but sensitive, tingling feeling along the left (outside) underside of my left kneecap. It runs from the top left side of my kneecap around the kneecap to the bottom left side to to the left dimple in the knee. The feeling seems to come from whatever's beside and underneath the left side of my kneecap.
I have full movement of my knee, it's just that this sensation drives me nuts sometimes. It's a similar sensation to having a body part fall asleep-it's not painful, it's just strange and bothersome.
What is it, is there a way to get rid of it, and should I see a doctor for it?
