Should I be worried?

So I have this really bad cold, probably the worst cold I've had in a long time.. Usually I wouldn't worry because i know you can't do much about a cold except rest and drink lots of fluids etc.

But over the last day or two, every time I've fallen asleep, I have woken up drenched in sweat, like I am talking absolutely soaked to the point that I wake up shivering and need to get out of those clothes. Normally I wouldn't worry but this hasn't happened to me before. And I'm only sleeping for hours at a time before waking up, and it happens every time. Should I see a Dr or is this type of thing normal? I also don't have a fever if that helps.
