I see many with the same symptom...appeared without being aware, pain outside of right knee ONLY when when forget and kneel down quickly. It feels like what I imaging gout to feel like - kneeling on glass - but without the swelling. Ice and heat don't help. Kneeling on a soft, spongy surface is fine if positioned carefully. Very sharp pain but leaves quickl, especially if rubbed. Been sitting with my knee bent at computer so slightly aware of it but normally not.
Nothing in the threads to date sounds like the problem.
