Small BB sized ball under skin on my shin

I just discovered a small lump the size of a BB which is about half way up my shin, on the front right where the tibia is nearest the skin. It is hard and moves smoothly around under the skin if you touch it, but always goes back to the same spot as if it's anchored there by some tissue.

It could be a lipoma, but apparently they are more common in areas with more body fat. It could also be a sebaceous cyst, but they are usually found in the upper part of the body according to Wikipedia.

When I go to the doc next should I get him to cut it out? If it is a cyst, apparently they can get infected some time down the road, and it might be better just to get it out.

It sounds like a cyst to me. I've had them on my thighs so I imagine one could be found on the shin. They're pretty easy to lance and treat. Your doctor will let you know.

I have one too. Was once told it was an alien implant.

But I think they are called ganglian cysts?

I have a big one on my wrist. They are harmless, just a collection of fluid that hardened.

Not a bad idea to have it checked out though.
