Hello and thanks for your query.
I shall make an effort to provide you with good professional recommendations specific to your questions.
Itchy hands do not present as their own condition.The cause may be exogenous or endogenous.
Causes may include
contact dermatitis, infection, done systemic diseases, certain vitamin & mineral deficiencies,
stress and
anxiety.
As you have short history I feel it is more in favor of contact dermatitis. You might have come in contact with some allergen unknowingly which might be responsible for your itchy hands.
I advice you to avoid wet work where ever possible, use emollients.
If it persists for another two more days or if
redness develops or itching intensifies, I advice you to see doctor immediately.
Yet again, I duly appreciate your query to me, I do hope that have found something useful to help you and I shall be glad to answer any further apprehensions.
Sincerely,
