Jammed Neck

For some unknown reason, I woke up on Tuesday with a slight ache on my neck, which developed in the next day into a crippling neck ache which restricted the rotational capabilities of my neck to about 45º. Even today, my neck isn't in a very good shape, and everytime I talk to someone I've to turn my whole body, reminding myself of FFVIII characters.

This has happened before, and it usually lasts a few days... though I have absolutely no idea what has caused it. I now just hope that my neck will be sufficiently twistable for Chinese New Year.
