Customer Question

I have a small sized hard and very mobile lump under the skin of my left shin - right below my knee to the right of the bone. I have no idea how I discovered it, nor do I have any idea how long it may have been there. By small - it's about the size of a b.b. and by mobile - it moves about an inch in different directions. It's actually slippery when I try to isolate it, constantly moving.I know it's hard to diagnose over the internet, but I am trying to discern if this is something normal / benign or something I should rush to a doctor for.

Hello and welcome I'm Dr Chip

Is it tender at all?

And no trauma involved?

Customer: replied 3 months ago.
It is not tender. Or I should say it wasn't when I discovered it, it is now, but I have been "playing" with it.No trauma, although years ago I did fracture my patella more than once.
Expert:  Dr. Chip replied 3 months ago.

OK thanks

Nothing at all serious like cancer if you were concerned about that

This is just a small benign cyst and it may go away soon

If it doesn't and it bothers you it can easily be removed under local anesthesia

Please let me know if you need any more information

the firmness / hardness of it should be of no concern?
Expert:  Dr. Chip replied 3 months ago.

No, some of these cysts can be very hard but again, not cancer
