So I was watching a little TV last night when I noticed that my thumb was shaking involuntarily when put into a specific position on the remote control.

Imagine the position like this. Hold your hand in the thumbs up position, with folded fingers towards your chest. Now, bend your thumb to a 90 degree angle. In this position, my right thumb shakes up and down. It's not severe, but it's there.

Now, I want to make a hypothesis about this. On my computer, I hold my mouse with my right hand and often find that I put my thumb at that angle on the left side of the mouse.

This is particularly worrying me because while I do spend a significant amount of time in front of a computer for school / work / entertainment, I'm 20 years old and extremely active - that is, weight lifting 3x a week and full court basketball at least 2x a week. I feel like those activities should be keeping my fingers strong.

Any ideas on what this could be? Hopefully it's not an early sign of carpal tunnel syndrome - I've done everything I can to avoid it in being active, taking multivitamins, etc.

Also, any suggestions on what to do? Seek medical help right away? Calcium supplements?
