Hi, I have had a similar problem with my
hands over the past 4 years (searching
for answers led me to your question). Although the itching has not really been a problem, it was a question I was asked by the doctors and it has been diagnosed 3 times as a fungal infection, similar to athlete's foot. I was given a topical anti-fungal cream, which can also be purchased over the counter check out Lotrimin, Neosporin AF or any of the like, you can see if these help.
