I have tendinitis in my right thumb. Shooting, stabbing, sharp pains that are alleviated neither with Aleve nor ice.
I use my BlackBerry to read news (OK, and Facebook) on my daily hour-each-way train ride. I just signed up for a library card so I can read other things on the train. No more mobile blogging for me.
Time to work the grip even more in my postures! But ouch this hurts!!!
