They look like props from an episode of ER, but these Doctor Bag hot and cold packs are perfect for some quick relief from strained muscles or a flare up of an old sports injury. Doctor Cool Bag is obviously the cold one that you keep in the fridge, while Doctor Hot Bag has a button you use to activate the warming gel for the first use. Just boil it in water for re-use for pain management without the goofy looking hot water bottle.

Buy for approximately $20.00 each.
