Bump on thumb

I've had this bump on my thumb for over 10 years.  I haven't really cared about it until recently since people seem to notice it more.  It doesnt itch or cause any pain.  I have a bad (nervous?) habit of picking at it though.  Can anyone tell me what this might be and if any OTC meds would help?

any ideas?

This just looks like excess cartilage/skin or a certain type of wart.
Next time you're at the doctor for a checkup or anything, ask him/her if they think it's appropriate to get it frozen off or removed.
Picking at it could cause an infection and that wouldnt be good!
Best of luck, David

I have the same bump.  Family doctor told me it's callus.  Have you found a way to get rid of it?

I also have the big bump on the knuckle of my right thumb.  Mine was caused by bowling.  I was also hoping to find out how to at least reduce it's size.  But it looks like nobody has an answer.  oh well.  looks like it will have to stay that way...
