When I am wearing long sleeve jumpers/shirts, more with woolen mix, I get electric shock when I touch any kind of metal. e.g door knob, car, railings, ... anything that's metal. Why do I get these shocks and is there any cure for that? Other person wearing same cloths don't get any shock and I feel quite embarrassed when other people look at that time with curious eyes. Doctor says don't touch metal and laughs.
