I tripped fell on my knees about 2wks ago both are tender left hurts really bad on and off they were already tender , off.left feels is it broken?

Lasting Knee Pain: If you fell 2 weeks ago and are still symptomatic, that suggests a pretty significant injury - particularly the way you are describing it "really bad". Many things could be wrong that would need an evaluation by a doctor and perhaps some imaging. Depending on the nature of the fall it could involve soft tissue, bone, or the joint itself. Hope this helps!
