yup, exactly what the subject title says. these weird 'pulses' would be completely random in where on the body they would be. I remember counting exactly how many times it would happen during 1 minute at one stage and i recorded, no joke, 71 zaps. Luckily it stopped after week but ever since then i have wondered why and how something as weird as that could happen to someone like me: no allergies, no medications, no diagnosed diseases. nothing. So i would love some kind of explanation please!
