I'm a long time lurker and this is my first post. My 10 year old DD has started complaining of having one excessively sweaty hand. It is down the side of her hand from the top of the little finger to the wrist. I've had a look/feel several times and it is indeed sticky and sweaty whilst her other hand is dry and feels a normal temperature. Dr Google has not shed any light. I'm wondering if I need to be concerned about this - it seems very odd!
