Pain-Relieving Gadgets -- Do They Work?

Muscles so tight your shoulders threaten to swallow your head whole. Ankles so swollen they'd gross out the Elephant Man.

Collins: "This thing looks hilarious! But every single migraine patient says that having the temples and back of head massaged makes them feel better. Even medical writings from Egypt talk about the benefits of tight bandages. … We've known for a long time that pressure on the head makes people feel better."
