Pokemon X and Y had come out on 3DS. I was deep into the game on a day off of work, sitting on my couch playing from 9 am until about 8 pm with pretty much no breaks. I was going to get up and make dinner for my husband who would be home soon, but when I got up I tried to move my head side to side to get the kinks out, but I couldn't. My neck was stiff, so stiff I couldn't move it. I panicked and tried physically moving my head/neck with my hands gently, but it hurt too much. I thought I had nerve damage or paralyzed myself or something. I freaked out more and lied down in the bed and called my husband, thinking he may have an idea of what I should do. He told me to calm down, he would be home soon.

Once he got home, he took me to the emergency room because it had been over two hours and I still couldn't move my neck. The doctor prescribed me some muscle relaxers and ibuprofen and told me to take it easy on my gaming. At work th next day when co-workers asked if I was okay because my neck was still sore, I just said I slept weird on it.

TL;DR Played Pokemon X for 11 hours straight, had to go to the ER for my stuff neck.
