Hi There, My Name Is La Tonya And My Husband

Hi there, my name is La Tonya and my husband has been diagnoised with liver cancer and has had 3 different back surgeries (1 surgery for the past 3 years). My question is this, he takes Nexavar (oral form of Chemo) and this causes him to have severe cramping of his hands and he is experiencing the hand and foot syndrome from the chemo medication. Do you have any suggestions that we can use to ease the discomfort of the cramping and the blistering and peeling skin of his hands.
