Hi, I have had a handful of episodes now where I will get what feels like twinges/zings/pulsations in my left arm, tongue and head. I also feel light headed, kind of like I m going to pass out but I never do. It s not dizziness and I ve noticed it more on my left side than right. The first time it happened, I had an EKG and labs drawn and nothing showed abnormal. The Dr. said she thought it may have been a virus. Well, that was over a month and half ago. I was thinking that maybe it was stress, but it started yesterday and I had nothing stressful going on at all, in fact it was a great relaxing fun day and today I feel it even worse. It s not painful, just uncomfortable and annoying but I just don t know why it keeps happening now. I also noticed today that it seems to get worse with movement. Any ideas of what this could be?? Thanks!
