I have heard some people on this forum say that ice packs, standing in front of the open freezer door, standing outside for a minute or two, keeping your skin lotioned up, and drinking lots
of water helps. Have your tried the anti itch ointment
Triamcinolone? It is a prescription that seems to help my husband's itching. He has also used Eucerin cream and Eucerin body wash, which seems to help.
