The current invention discloses a treatment device having a heat source, a power source, a heat applicator and a lighting mechanism. The power source includes at least one battery having superior properties such as prolonged electricity production and prompt recharging. The heat applicator includes a heat conductive layer made from nanofibers, providing highly efficient heat distribution to the targeted regions. The lighting mechanism employs light emitting nano fibers to treat targeted regions. The power source provides energy to the light source, which generates light so that the applicator may distribute to an injury site or wound bed of a user. The heat source may be an exothermic chemical reaction designed to last for several hours supplying heat to the treatment device or an electronically produced heat. The treatment device further comprises a plurality of electrodes for electrical stimulation treatment.
