Question : My son is 29 and has just noticed a hard lump, like bone below his left knee cap. He has no pain but just noticed it while sitting in a pair of shorts. He is freaking out and sounds like a 2nd year med student. He has an appointment with a general next week, but he is having a diffult time. Concentrating or doing anything else but expecting the worse. Please help

Brief Answer:
May be a bony spur.

Detailed Answer:
Hi
Thanks for your query.
Noted the history related to your 29 year old son.
The hard bony like lump below the left knee can be:
Spur from the tibial tuberosity.
This could have been due to previous trauma.

Since this is painless, it is most probably benign.
But can be confirmed by clinical evaluation, X-ray and other investigations.
The information on internet is very disturbing, if reads more, more will be confusion and fear.
Hence I would advise him to take this as very benign disease unless proved otherwise.

I hope this answer helps him.
Please give feedback of the investigations and advise him to stop internet search.
