I was also thinking allergy. Maybe, sometimes, mild ones can be made worse by a viral infection. Or, at least, become more apparent.
Or maybe it's flatness? Extra pillows (foam ones, in case it is allergy) or lying face down sometimes helps. Of course, you have to get used to sleeping face down and flat, but it can be very helpful with breathing and so on.
