Hi, I have a pot belly and have used slenderone twice on a very low setting (20). For 1 1/2 years have had recuuing The physio (a yea ago said one side was stronger than the other and causing a twist. The day after slendertone, I have stiff calf muscles, particularly the right one, mild pain across my lower my lower back, and localised pain inside my hips ) paticularly the right one. Is this normal?
