instruction: hello doc every night for almost weeks now I experienced itchy hands like only every night when I am about to sleep so itchy that I cannot sleep I do not notice any insect bites or red spots or rashes on my skin I really cannot sleep well every night because of this I think the itchiness is coming from the inside of my hands help me please I tried taking cetirizin because I thought it may ease the itchiness but nothing happens thank you
