Hi, may I ask about some certain body tinglings? My muscles have been tingling and its been starting since the beginning of the Summer. It will start randomly can will do so for 2-10 seconds per place. The place that will tingle will be random, [head, legs, knee , arm , armpit, back of neck] I m not quite sure whats going on, it makes me feel rather weak. I ve heard vitamins as an option. Is it something else? Thank you very much.
