Are you sure you can wait until next month (((((((bebop))))))?

It doesn't sound very pleasant, and it kinda sounds worriesome at the same time. Have you changed anything med-wise, health-wise, eating-wise recently that may be the cause?

Headaches aren't any fun. When I was experiencing mind-bending ones, I had to get to a neuro doc ASAP, since I've got neurological things, and we had to make sure I wasn't going to need surgery. Random painful headaches suck... especially with little explanation.
