today i had an experience with my legs becoming weak. at first i had just got outta bed and walked outside, when i did i felt as if my legs were becoming heavy and numbish and it kinda hurt too i tried to walk inside the house fast so i wouldnt collapse outside, i sat down and it went away. i went and layed down and then got back up again, when i did i started seeing black dot and i was starting to get a tingly sensation throughout my body and my legs gave out and i started to jerk back and forth and while i was on the floor my eyesight was nothin but black dots and i was tingly all over. what could be wrong with me i have been experiencing this all day. even when i sit down now i can still feel my legs get numb and heavy
