Communication devices, systems and methods

A treatment device, comprising:

• a wearable body having a distal surface and a proximal surface, the distal surface comprising a biocompatible adhesive material arranged to removably attach the wearable body to an area of skin of a user;
• a power source including a rechargeable battery;
• and
• an electrical generator element and a heat generator element coupled to the wearable body, the electrical generator element and the heat generator element being independently operable to convert electricity from the power source into an electrical energy and to communicate the electrical energy to muscles and pain receptors of the user, and to convert electricity from the power source into a heat flux and to communicate the heat flux to temperature receptors of the user.
