An economical dual modality system can be manufactured and used in a method including the steps of assembling a system including a durable energy subsystem and a replaceable thermal subsystem, activating the replaceable thermal subsystem, attaching the system to a desired treatment area of a user's body, and activating the durable energy subsystem. The durable energy subsystem is arranged and configured to deliver energy, and the replaceable thermal subsystem is arranged and configured to be coupled to the durable energy subsystem arranged and configured to deliver thermal energy. The replaceable thermal subsystem delivers thermal energy to the desired treatment area at a predetermined temperature range for at least 30 minutes, and the durable energy subsystem delivers energy from the group consisting of non-visible light electromagnetic radiation, visible light radiation, electromagnetic field, microcurrent, electrical stimulation, iontophoresis, sonophoresis and combinations thereof independently of the thermal energy.
