I have a very painful wrist (waiting to see if its going to swell). I still dont know how the following happened. I picked up my phone book and was holding it about to look something up.. when suddenly the phone book (the weight of it I guess) caused my wrist to be bent right back. Usually if my hands give out I'll just drop something (that used to happen a lot but dont tend to happen to me anymore.. well much anyway). Im still confused about what happened with my wrist which has caused me to hurt myself. So Im now having to type without moving my actual wrist. What next.. Im a bit shocked Ive injured myself with a phone book. (its the other hand to the one I blistered the other day).
