For almost a year, I had sore fingers from using the mouse.  After a day of clicking and wheeling, tips of my index finger (used to press left mouse button) and middle finger (used to press right mouse button and roll mouse wheel) got swollen and I felt pain when I used them.  I usually had to rest my fingers on a cold pack to get the swelling down.

The solution I came up with last night was to put one of those rubbery band-aids over the mouse buttons.  Wow, what a difference they made.  It was like discovering Nike Air after running barefeet my whole life.  Next week, I am going to try one of those shock-absorbing pads for foot.  I wish I can put them on the keyboard too, but labels cause problems.

Gee, I think there might be a market for these sort of things.  Maybe security industry's terror marketing tactic can be used.  If a doctor announced that minute shocks to finger tips through prolonged use of mouse and keyboard can damage fingers irreversibly, millions will rush out to get these finger shock-absorbers.  Woohoo!
