Hi, I m 19 and just 3 days ago I believe I ve had some sort of stomach virus/strain of influenza - my body rejected anything I tried to ingest. 2 days ago I puked 6-7 times, afterwards I called my aunt ( a nurse ) to see what I should do and then I had small sips of 7-up, I feel much better now in terms of being able to eat. However right after I stopped puking, a new symptom appeared (yesterday) I feel this electric shocks in small amounts throughout my body. It feels like pins and needles, I m thinking it might have to do with my circulation since I was dehydrated while having the symptoms of stomach flu. I still have these electric shocks/pins and needles, they started out in my hands, then moved throughout my body. They are worst when I do high intensity exercises or physical activities, and now have become painful and a nuisance. What do I have?
