I have a small hard lump (feels like bone) directly below my right kneecap.  Its not under or behind the kneecap, but below.  It does not hurt all all when I touch it, however, last night i felt intermittent pain sensations in the area as I laid in bed.  Also, I can only feel the hard lump when I bend me knee.Any thoughts would be greatly appreciated!  Thanks
Hi. Thanks for your query and an elucidated history. This can be problem with the tendon. There can be a fibrous band or a calcification of the tendon. This is confirmed by X-ray / Ultrasonography. Take an opinion of the Orthopedic Surgeon and follow his advice.
