A device and method are shown for treating a localized area of pain in the human body. A heating pad is applied to the localized area, the pad having a layer of matrix material which is actuable by exposure to microwave energy. The heating pad is heated by exposure to microwave energy to a temperature above ambient prior to application to the localized area. The microwaveable layer is sandwiched between upper and lower elastomeric layers formed from materials which are non-absorptive of microwave energy.

A method of treating a localized area of pain in the human body, comprising the steps of: applying a heating pad to the localized area, the heating pad comprising at least one layer of microwaveable silicone rubber which has been heated by exposure to microwave energy to a temperature above ambient

A method of treating a localized area of pain in the human body, comprising the steps of: applying a heating pad to the localized area, the heating pad comprising at least one layer of microwaveable silicone rubber which has been heated by exposure to microwave energy to a temperature above ambient prior to application to the localized area the microwaveable silicone rubber comprising a polyorganosiloxane gum having blended therein about 5 to 30 parts per 100 parts of gum of zinc oxide as an electromagnetic absorptive material and from about 10 to 260 parts per 100 parts of gum of a filler material; and wherein said one layer of microwaveable silicone rubber is sandwiched between an upper and a lower elastomeric layers formed from materials which are non-absorptive of microwave energy, said upper and lower elastomeric layers having a lower relative extending filler content than said microwaveable silicone rubber layer, whereby said heating pad is heatable to approximately 170°F. by exposure to a 700 watt microwave oven at 100% power for 3 minutes, the pad requiring approximately 45 minutes to return to 60°F.
