Mate I have got the same problem! Its an allergy, and gets better and worse again all the time so have reverted to always wearing gloves now, but make sure you get the ones that are specially for sensitive skin otherwise the latex and powder can make things worse. Try using other products and see how it goes but from experience once you get it, it is here to stay if you have what I have.
Use EC45 cream which really helps, and avoid sun cream and other oily products too. Don't mean to sound gay but it is REALLY unpleasant having your hand looking like a lepers and very sore and uncomfortable too.
