Knee Only Hurts When Going Downstairs And Sometimes Feels Like It Is Loose From The Bottom Of My Leg When I Lift It. Sometimes It Feels Ok. Then Bothers Me Again. No Swelling, No Pain At Rest. Mostly No Pain When Walking. Feels Unstable. Can You Help?

I have a similar thing....going downstairs I feel a very sharp pain on the right side to the center of my kneecap.
It has been going on for a week or so  AND NOW, its starting to hurt when I am just walking    I am hoping someone answers here!  :(  please

I have the same thing! For a week or so my right knee has been giving me trouble. I would describe it as a sharp pain in the anterior lateral area, between the patella and lateral collateral ligament (feels like a meniscal injury) ONLY WHEN I DESCEND STAIRS. Going up stairs and walking cause me little to no pain, and rest seems to help alleviate aggravation. I am a college student who exercises often (sports/free-weights) and as you can imagine, am constantly walking up and down flights of stairs to dorms and classes. ( I do have history of injuries with this knee (ACL reconstructive surgery, recurring instability post-op) but this symptom is new to my arsenal of pain )

How old are you? Do you play sports? And whats you BMI? It could be a number of things most likely a small Meniscus Tear...not to serious but get an MRI just in case...

have your knees x-rayed asap...could be ligament damage....

I have the same problem. My knee is fine for like twenty steps or so, but then suddenly it gets this pain when I walk. And it kills when I walk down the stairs, not so much walking up them. I hope somebody answers this as well
