Last night whilst at work I started getting tingling and pins and needles in my left hand. When I got home about 1030 this had gone into both hands and slightly in my arms. When i woke this morning i couldnt feel it but as soon as i started thinking about it (5mins) it came back. I'm getting really worried now I think this is something wrong with my brain. If anyone has experienced this how long has it lasted. I'm really scared.
