I am 17 and I was laying down I sat up and tried to use my computer when I realized I could barely type my middle and ring finger on my left hand keep trembling. when I try to use them. It is very frustrating. I have been getting odd tingles on my body for a while now. I will get tingles on both my arms and on and in my head it gives me goose bumps and makes all my hairs rise. I am starting to get frustrated with the trembling especially. Does anyone know what could be going on?
