The present invention is a disposable garment, such as a glove, a sock, or a shoe, for treating foot or hand inflammation or disease. In a preferred embodiment, the garment comprises a flexible outer cover that is nonporous and an inner layer closely adhered to the inside of the outer cover. The outer cover may preferably have a flexible closure at the level of the ankle or wrist, arranged such that liquids will be retained therein. The inner layer serves as a reservoir for a selected therapeutic product, and preferably comprises a bladder. Preferably, the bladder has a perforation, and may be disposed within the inner layer in a position allowing a user to apply pressure to bladder with his foot or hand. A therapeutic product in liquid form is stored within the reservoir, and is released upon application of pressure by the user's foot or hand.
