wherein the device contains a motor and a pushing rod that supply the movement that results in percussion of a removable heating/cooling attachment and a removable percussion attachment; wherein the front of the device connects to the removable heating/cooling attachment that contains an electronic component to control heating or cooling and a cooling fan; wherein the removable heating/cooling attachment can be used for heating or cooling; wherein a housing shell for the heating/cooling attachment is made of plastic, foam, or metal, or any combination of plastic, foam and metal; wherein the front part of the heating/cooling attachment is made of metal that has the capability to be in contact with human skin in order to provide either heating or cooling at fixed or adjusted degrees that are optimal for physical therapy and/or blood circulation; wherein the removable heating/cooling attachment can be replaced by the removable percussion attachment that is used for percussion; wherein the removable percussion attachment can be placed on the skin of a user in order to provide percussion at fixed or adjusted speeds that are optimal for physical therapy. ## Claims ### Claim 1 A portable percussion massager comprising: a housing;
