I do pretty much everything wrong in terms of ergonomic working. No wrist rest, no typing technique, sit however fits the day. The only thing I don't have in common with the OP is that I'm constantly hot. Sitting in a room with no heating at 1000m above sea in the Alps right now, wearing a light track suit and only registering a mild cold. I haven't turned on heating in ages, actually.
The article does suggest psychosomatic causes more than anything, imho. Especially people with neither medical training (me included) or prior contact with that phenomenon (me excluded) often seem to think about this as a question of willpower, a conscious decision or a few sessions with a therapist. I beg to differ. If your hands pain you to the point of forcing you to change careers and there's no physiologically pinpointable reason, I don't see how the most complex parts of our bodies could not play a leading role.
