help me!

My cuticles keep getting infected for no apparent reason... it first started on my index finger on my right hand, then moved to the middle, then ring, then pinkie of that hand. It never traversed to my left hand until a couple of days ago. I went to the dermatologist about a month or so ago, and got some special cream for it, but it still keeps reoccurring. I don't have my hands in water a lot, so that's not the problem.. has anyone had a problem like this?
