DH has a skin disease on the finger of one hand. It's extremely painful and the only thing which eases the pain is keeping it warm. He's tried gloves but they're impossible to wear all day especially when working and they don't really do much. Carrying a hot water bottle around all day isn't practical either.
Any suggestions? Heart breaks for him as it's getting worse. Doctors are aware of his pain, he's sadly on the waiting list for an amputation.
