my 2 year old toddler has been holding his wrist and saying it hurts, so i take it and squeeze it and move it around and he doesn't make a sound to indicate that it hurts, but sometimes when he is crying he holds it, or when he is just standing he will hold it and complain of pain, this has been going on for about 6 weeks now. it can't be fractured or a ligament damaged or dislocated could it?
